Based on multi-bit, delta-sigma modulation, it a llows infinite sample rate adjustment between 32 kHz and 192 kHz. The ADC input path allows control of a number of fea- tures. The microphone input path includes a selectable programmable-gain pre-amplifier stage and a low-noise MIC bias voltage supply. A PGA is available for line and microphone inputs and provides analog gain with soft ramp and zero cross transitions. The ADC also features an additional digital volume attenuator with soft ramp transitions. The stereo headphone amplifier is powered from a sep- arate internally generated positive supply, with an integrated charge pump providing a negative supply. This allows a ground-centered analog output with a wide signal swing and eliminates external DC-blocking capacitors. The integrated digital audio interface receiver and trans- mitters utilize a 24-bit, hi gh-performance, monolithic CMOS stereo asynchronous sample rate converter to clock align the PCM samples to/from the S/PDIF inter- faces. Auto detection of non-PCM encoded data disables the sample rate conversion to preserve bit ac- curacy of the data. In addition to its many features, the CS4207 operates from a low-voltage analog and digital core, making this part ideal for portable syste ms that require low power consumption in a minimal amount of space. The CS4207 is available in a 48-pin WQFN package in both Automotive (-40°C to +105°C) and Commercial (- 40°C to +85°C) grades. The CS4207 Customer Demon- stration board is also available for device evaluation and implementation suggestions. Please refer to “Ordering Information” on p 142 for complete ordering information.

CODEC RESET AND INITIALIZATION

4.1 Link Reset

A Link Reset is a system controller generat ed assertion of th e HD Audio Bus RESET signal. A Link reset will cause some of the HD Audio bus interface logic to be initialized. Following a Link Reset, the CS4207 will perform the Codec Initia lization request sequence. Many of the codec se ttings will remain unchanged following a Link Reset. See “Register Settings Across Reset Conditions” section on page 28 for more de- tails. When the codec has detected a Link Reset condition, all converter widgets and pin widgets will transition to a low power operating mode, if previously in D0. The actual power states reported will remain unchanged, i.e. if in D0 or D3 prior to Link Reset, the widget stays in D0 or D3. If enabled, presence detection will con- tinue to sense any impedance changes and issue a power state change request to the Link prior to asserting an Unsolicited Response.

4.2 Function Group Reset

Because the CS4207 supports the Extended Power State Support (EPSS), a single occurrence of the Func- tion Group Reset command will NOT cause the Audio Function unit and all associated widgets to initialize to the power-on reset values (as described in the HD Audio Specification, Rev. 1.0). When the CS4207 re- ceives a single Function Group Reset verb, the codec will issue a response to the verb to acknowledge re- ceipt, and reset each input/output converter widget’s Stream Number and Lowest Channel Number to the default (0h). No other se ttings are modified. See “Register Settings Across Reset Conditions” section on page 28 for more details. The CS4207 will respond to the newly created “Double Function Group Reset” (as defined in HDA015-B, March 1, 2007) and will reset most of the register settings to their power on defaults. This “Double Function Group Reset” will not affect the HD Audio bus interface logic or the unique codec physical address, which must be reset with the link RESET signal. Therefore, the codec will not initiate a Codec Initialization se- quence on the link. In addition, the Configuration Default settings will not be reset with a “Double Function Group Reset”. This new reset condition is created by sending two Function Group resets back to back. The “Double Func- tion Group Reset” is defined as two (2) Function Group Reset verbs received without any other intervening verbs. The Function Group Reset verbs are not required to be received in sequential frames, but there must not be any other verbs received in frames between t he receipt of the Function Group Reset verbs. There are no implied time outs between the time the first Function Group Reset is received and the second Func- tion Group Reset verb.

4.3 Codec Initialization

Immediately following the completion of a Link Reset sequence, the CS4207 will initiate a codec initialization sequence. The purpose of this init ialization sequence is to acquire a unique address by which the codec can thereafter be referenced with Commands on the SDO signal. During this sequence, the Controller pro- vides the codec with a unique address using its attached SDI signal. If the CS4207 codec is in a low power D3 state and enabled to support a presence detect event, it will retain its unique address while in that low power state. If RESET is de-asserted high, and BITCLK and SYNC are running at the time of a presence detect event, the codec will signal an unsolicited response. When put into the D3 low power state and enabled to support a presence detect event, with the link in the reset state (RESET is asserted low), th e CS4207 will post the occurrence of a wake event and request a power state change by signaling a power state change request and initialization request. It will reestablish the connection with the controller by performing a “Codec Initialization request”.

If RESET is asserted low, and BITCLK and SYNC are not running at the time (defined as link low power state), the codec will signal the power state change request and initialization request asynchronously by as- serting SDI high continuo usly until it detects th e de-assertion of RESET . It will then asynchronously drive SDI low with the de-assertion of the RESET. With the RESET signal high, the codec will reestablish the con- nection with the controller by performing a “Codec Initialization request”.

4.4 D3 Lower Power State Support

The D3 low power state allows for, but does not require, the lowest possible power consuming state under software control, in which Ex tended Power States Supported (EPSS) requirements can be met. While in the D3 state, the CS4207 will retain sufficient operational capability to properly respond to subsequent soft- ware Get/Set Power State commands (Verb ID=F05h/705h) to the Audio Function Group (Node ID = 01h). In addition, while in the D3 power state, Link Reset and “Double Function Group” reset are supported. All other Get/Set commands will be ignored while the codec is in the D3 power state. Widgets reporting an EPSS of ‘1’b will transition from D3 state to D0 state in less than 10 milliseconds (this is a target). This interval is measured from the response to the Set Power State verb that caused the tran- sition from D3 back to fully operational D0 state. It is permissible for the audio fidelity for analog outputs to be slightly degraded if audio playback begins im- mediately once the fully operational state is entered. However, audio fidelity will not be degraded 75ms after the transitioning to D0 state.

4.5 Extended Power States Supported (EPSS)

EPSS indicates that the Audio Function Group or a particular Widget supports additional capabilities allow- ing better low power operation. The CS4207 will report EPSS support at the Function group level and will enable low power operation for all Input and Output Converter Widgets, and the following pin widgets which are capable of reporting presence detection: – Headphone pin widget (node ID 09h) – Line Out 1 pin widget (node ID 0Ah) – Line In 1/Mic In 2 pin widget (node ID 0Ch) – Mic In 1/Line In 2 pin widget (node ID 0Dh) – S/PDIF Receiver Input pin widget (node ID 0Fh). The following requirements will also be implemented by each input/output converter widget and the above listed pin widgets:

Report PowerCntrl set to ‘1’b and support the Supported Power States verb.
Jack Presence state change repo rting (when enabled) will operate regardless of the Widget and Audio Function Group power state.
Reporting of presence state change and issuing sys tem wake when the link clock (BITCLK) is not oper- ational is supported.
The S/PDIF Receiver to S/PDIF Transmitter digital loop-through (no clock re-timing) will continue to op- erate (if enabled) even though any one, or all of the S/PDIF Receiver Input Converter Widget, S/PDIF Transmitter Output Converter Widget or S/PDIF Receiver Input Pin Widget enters into low power states. This digital loop-through will also continue to operate if the Audio Function Group is placed in the D3 low power state, during a Link Reset, and even if the HD Audio BITCLK is stopped.
Dependencies between converter wid gets and associated pin widgets will not cause unexpected results when one node of the dependency is placed into D3 state. The diagrams and tables below demonstrate typical audio streams.

4.6 Power State Settings Reset (PS-SettingsReset)

PS-SettingsReset is reported as set to one ‘1’b when, during any low power state transition the settings that were changed from the defaults (either through software or hardware) have been reset back to their default state. When these settings have not been reset, this is reported as ‘0’b. The conditions that may reset set- tings to their defaults are: 1. Power On; always sets the PS-Setti ngsReset to ‘1’b for all widgets that report EPSS set to ‘1’b and that have host programmable settings and reset all settings. 2. Double Function Group Re set: sets PS-SettingsReset to ‘1’b for all widgets that report EPSS set to one (1) and that have host programmable settings and resets all settings. Single Function Group Reset, Link Reset or BITCLK stopped will not cause the PS-SettingsReset bit to be set to ‘1’b. All settings should persist across these events. The PS-SettingsReset will be reported at the individual widget level and at the Audio Function Group level. The PS-SettingsReset bit for the Audio Function Group is handled differently than at the widget level. For the Audio Function Group the PS-SettingsReset bit is set to ‘1’b when any widget sets its PS-SettingsReset to ‘1’b. The Audio Function Group’s PS-SettingsReset bit is the logical “or” of all the PS-SettingsReset bits, but is latched so that it can be reset independently and not require all the individual widget PS-SettingsReset bits be reset. This allows a simple poll by the host software to detect when some settings have been re- set/changed. For widgets that do not support the EPSS bit, reporting PS-SettingsReset is not required. If the PS-SettingsReset bit is set to ‘1’b, then this bit for individual widgets, will be cleared to ‘0’b on receipt of any “Set” verb to that widget; or after responding to a “Get” Power State verb, to that widget. Bit settings within converters and pin widgets that software changed from their defaults will not be changed by hardware across any Dx state transition, single function group resets or link resets. Table 1 on page 28 outlines the handling of setting persis tence should be performed across Dx states, clock stopping and re- sets. Because the CS4207 supports EPSS, the use of PS-Settings Reset to report that settings have been reset (changed) is required.

not running, then the request to wake the Link will occur within 10ms. continuously for at least 250ms. sition to active power state. Figure 7. Jack Presence Detect Circuit

If the codec has detected that the link is entering a Link Reset state (see description below), all Unsolicited Response requests will be buffer ed. Once the link is in th e Link Reset state, with RESET asserted low, the codec will request a power state change and initialization request. Following the codec initialization cycle where a unique address is provided to the CS42 07, the codec will then wait for the first verb to be received before issuing the Unsolicited Response to prevent the response from being lost due to software transition to active power state. The Link Reset entry sequence is defined as follows: 1. The HD Audio Bus controller synchronously completes the current frame but does not signal Frame Sync (SYNC) during the last eight SDO bit times. 2. The HD Audio Bus controller synchronously asserts RESET four (or more) BITCLK cycles after the completion of the current frame. 3. BITCLK is stopped a minimum of four clocks, four rising edges, after the assertion of RESET. In the event of a system bus (PCI Bus) reset, the above sequence does not complete, and RESET is asyn- chronously asserted immediately and unconditionally. When the codec returns to D0 from the D3 lower power state, the state of the presence detection bits will be correct. If the codec power has been removed, the state of the presence detection bits will be reset to the default value and the codec WILL NOT report this by setting the PS-SettingsReset bit for the affected Pin Widget(s). (HDA015-B, March 1,2007 stays that the PS-SettingsReset bit will be set for the affected Pin widget).

5.1.2 S/PDIF Receiver Presence Detect

The presence detect scheme for the S/PDIF Receiver will use the lo gic state transition of the “LOCK” or “UNLOCK” indicator for the incoming digital stream. The “LOCK” and “UNLOCK” indicators are sticky bits (edge-triggered) which indicate the current state of the receiver. These bits are located in the Vendor De- fined Verb at F70, see “S/PDIF RX/TX Interface Status (CIR = 0000h)” on p 128. When the S/PDIF Re- ceiver Input Converter Widget is “enabled” and the “LOCK” indicator is a “1”, then the Presence Detect bit in the Pin Sense register will be se t to ‘1’. The S/PDIF IN Converter Widget (NID=07h) and the S/PDIF Receiver pin widget (NID=0Fh) must be in the D0 state to support presence detect using this method de- scribed. With an incoming valid S/PDIF signal applied to the SPDIF_IN pin, the “LOCK” status will be valid approx- imately 200 S/PDIF frames following the receiver being enabled.

There are no dependencies unknown to software between nodes that would inhibit transitioning to the requested power state. 7:4 Read Only 0011b Power State Actual (PS-Act): This field indi- cates the actual power state of the referenced node. The default state is D3. 3:0 Read/Write 0011b Power State Set (PS-Set): Writes to these bits set the Audio Function Group to the Power State as described below: PSS = ’0000’b; D0 - Fully on. PSS = ‘0001’b; D1 - Not Supported PSS = ‘0010’b; D2 - Not Supported PSS = ‘0011’b; D3 - Allows for lowest possible power consumption under software control. See “D3 Lower Power State Support” on page 25 for more information. PSS = ‘0100’b; D4 - Not Supported

PS-Set is a Power State field which defines the current power setting of the referenced node. Since this node is an Audio Function Group node, the actual power state is this setting. Setting this field to the D3 state for the Audio Function Group node will force all other nodes with power state control to the D3 state. If the Power State field for this node is set to D0, then the individual power state for each converter will be uniquely controlled via the corresponding node Power State field. PS-Act is a Power State field which indicates the actual power state of the refe renced node. Within the Audio Function Group node, this fi eld will always be equal to the PS-Se t field (modulo the time required to execute a power state transition). PS-ClkStopOk is reported as a ‘1’b when the codec is capable of continuing proper operation in the ab- sence of the HD Audio Bus BITCLK. This bit is reported only at the Audio Function Group level and is reserved at the widget level. After accepting a low power state transition request (D3 state) to the Audio Function Group Node, the codec will begin ramping dow n all the audio converters. During this time, the PS-ClkStopOK bit will be set to ‘0’b to signify that the bus BITCLK can not be stopped. Once all the con- verters have been ramped down, the codec will update the PS-Act bits to reflect the ac tual transition to the D3 state and will then set the PS-ClkStopOk bit to a ‘1’b to report the ability of the Codec to operate correctly while in the low power state with the BITCLK stopped. While in the low power D3 state, and with the bus BITCLK stopped, the pin widgets of the codec which were enabled to support unsolicited respons- es will continue to operate.

6.6.10 Digital Converter Control

Get Parameter Command Format: Note: Address F0Eh is not supported. Set Parameter Command Format: Response Format: The S/PDIF IEC Control (SIC) bits are supported in one of two ways. In the first case referred to as “Codec Formatted SPDIF,” on an input PCM stream of less than 32 bits, the co dec strips off the SIC bits before transferring the samples to the system and puts them in the Digital Converter Control for later software access. In the second case, referred to as “Software Formatted (or Raw) SPDIF,” on a 32-bit input stream, the entire stream is transferred into the system without the codec stripping any bits. However, the codec must properly interpret the Sync Preamble bits of the stream and then send the appropriately coded preamble. The IEC60958 specification, Section 4.3, “Preambles,” defines the preambles and the coding to be used.

PS-Set is a PowerState field which defines the current power setting of the referenced node. Since this node is of type other than an Audio Function Group node, the actual power state is a function of both this setting and the PowerState setting of the Audio Function Group node under which this node was enumer- ated (is controlled). PS-Act is a PowerState field which indicates the actual power state of this node. Within the Audio Func- tion Group node, this field will always be equal to the PS-Set field (modulo the time required to execute a power state transition). Within this type of node, this field will be the lower power consuming state of either a) the PS-Set field of the currently referenced node or b) the PS-Set field of the Audio Function Group node under which the currently referenced node was enumerated (is controlled).

6.7.8 Digital Converter Control

Get Parameter Command Format: Note: Address F0Eh is not supported. Set Parameter Command Format: Response Format: The S/PDIF IEC Control (SIC) bits are supported in one of two ways. In the first case referred to as “Codec Formatted SPDIF,” if a PCM bit stream of less than 32 bits is specified in the Converter Format control, then the S/PDIF Control bits, including the “V,” “PRE,” “/AUDIO,” and other such bits are embedded in the stream by the codec using the values (SIC bits) from the Digital Converter Control. In the second case referred to as “Software Formatted (or Raw) SPDIF,” if a 32-bit stream is specified in the Converter Format control, the S/PDIF IEC Control (SIC) bits are assumed to be embedded in the stream by software, and the raw 32-bit stream is transferred on the link with no modification by the codec. However, the codec must properly interpret the Sync Preamble bits of the stream and then send the ap- propriately coded preamble. The IEC60958 specificat ion, Section 4.3, “Preambles,” defines the pream- bles and the coding to be used. So ftware will specify the “B,” “M,” or “W” (also known as “X,” “Y,” or “Z”) preambles by encoding the last four bits of the preamble into the Sync Preamble section (bits 0-3) of the frame. The codec must examine the bits specified and encode the proper preamble based on the previous state. The previous state is to be maintained by the codec hardware.

VCFG (Validity Config.): Determines S/PDIF transmitter behavior when data is not being transmitted. When asserted, this bit forces the de-assertion of the S/PDIF “Validity” flag, which is bit 28 transmitted in each S/PDIF subframe. This bit is only defined for Output Converters and is defined as Reserved, with a Read Only value of 0 for Input Converters.  If “V” = 0 and “VCFG”=0, then for each S/PDIF subframe (Left and Right) bit[28] “Validity” flag reflects whether or not an internal codec error has occurred (specifically whether the S/PDIF interface received and transmitted a valid sample from the High Definition Audio Link). If a valid sample (Left or Right) was received and successfully transmitted, the “Validity” flag should be 0 for that subframe. Otherwise, the “Validity” flag for that subframe should be transmitted as “1.”  If “V” = 0 and “VCFG” = 1, then for each S/PDIF subframe (Left and Right), bit[28] “Validity” flag reflects whether or not an internal codec transmission error has occurred. Specifically, an internal codec error should result in the “Validity” flag being set to 1. In the case where the S/PDIF transmitter is not receiving a sample or does not receive a valid sample from the High Definition Audio Controller (Left or Right), the S/PDIF transmitter should set the S/PDIF “Validity” flag to 0 and pad each of the S/PDIF “Audio Sample Word” in question with 0’s for the subframe in question. If a valid sample (Left or Right) was received and successfully transmitted, the “Validity” flag should be 0 for that subframe.  If “V” = 1 and “VCFG” = 0, then each S/PDIF subframe (Left and Right) should have bit[28] “Validity” flag = 1. This tags all S/PDIF subframes as invalid.  “V” = 1 and “VCFG” = 1 state is reserved for future use.  Default state, coming out of reset, for “V” and “VCFG” should be 0 and 0 respectively.

V (Validity): This bit affects the “Validity flag,” bit[28] transmitted in each subframe, and enables the S/PDIF transmitter to maintain con- nection during error or mute conditions. The behavior of the S/PDIF transmitter with respect to this bit depends on the value of the “VCFG” bit. DigEn (Digital Enable): Enables or disables digi- tal transmission. A 1 indicates that the digital data can pass through the node. A 0 indicates that the digital data is blocked from passing through the node, regardless of the state.

Response Format: PS-Set is a PowerState field which defines the current power setting of the referenced node. Since this node is of type other than an Audio Function Group node, the actual power state is a function of both this setting and the PowerState setting of the Audio Function Group node under which this node was enumer- ated (is controlled). PS-Act is a PowerState field which indicates the actual power state of this node. Within the Audio Func- tion Group node, this field will always be equal to the PS-Set field (modulo the time required to execute a power state transition). Within this type of node, this field will be the lower power consuming state of either a) the PS-Set field of the currently referenced node or b) the PS-Set field of the Audio Function Group node under which the currently referenced node was enumerated (is controlled).

APPLICATIONS

7.1 HD Audio Interface

7.1.1 Multi-Channel Streams

The CS4207 codec supports multi-channel streams (str eams with sample blocks containing more than two samples), on both inbound and outbound frames. Each of the 5 output converter widgets (DAC1/2/3, S/PDIF TX 1/2) can be associated with an individual stream, or multiple widgets can be grouped to share the same stream. A mix of shared and individual stre ams is also supported. Furthermore, the order in which channels are assigned to each widget is not constrained by design. However, the following limita- tions exist and must be avoided:

a stream cannot contain channe ls that are not associated with an y widget (unused channels), unless those channels appear last within the stream packet, after all other channels
the same channel cannot be associated with more than one widget The same capabilities and li mitations exist for the 3 input converte r widgets (ADC1/2, S/PDIF RX). The following table gives some examples of valid and invalid stream formats: The curly brackets { } delineate each stream packet. The letters within curly brackets designate each channel within that stream packet. For instance the sequence “{A, B, C, D} {E, F}” denotes two streams - one stream consisting of 4 channels A-D and one stream consisting of 2 channels E-F.

7.2 Analog Outputs

7.2.1 Analog Supply Removal

In order to reduce audible artifacts, the analog reference is always powered up, even if the AFG has been transition-ed into D3 state. For maximum power savings during D3, it may be desirable to completely re- move the analog supplies on the system level. Doing so would cause an uncontrolled discharge of the internal reference and hence audible artifacts, and must therefore be preceded with a controlled reference ramp-down, which is initiated by setting the PDREF bit in the DAC Configuration (CIR = 0003h) register of the Vendor Processing Widget (Node ID = 11h).

7.3 Digital Mic Inputs

For each ADC, the data from the digital mic input pin widgets are multiplexed with the data from the analog line/mic input pin widgets, and only one pin widget can be selected at any given time. Furthermore, the data pins for the DMIC interface (DMIC_SDA1/2) are multiplexed with the GPIO0/1 pins and default to GPIO. In order to successfully setup the data path for a digital microphone, the following steps have to be followed: Stream Format DAC1 DAC2 DAC3 SPDO1 SPDO2 comment {A,B} {C,D} {E,F} {G,H} {I,J} A, B C, D E, F G, H I, J indiv. streams, in-order assignment {A, B, C, D, E, F, G, H, I, J} A, B C, D E, F G, H I, J shared stream, in-order assignment {A, B, C, D} {E, F} A, B C, D E, F - - mixed shared and indiv. streams {A, B} {C, D} - - C, D - A, B indiv. streams, out of order assignment {A, B, C, D, E, F, G, H, I, J} G, H E, F A, B I, J C, D shared stream, out of order assignment {A, B, C, D} - - - C, D - invalid: leading unused ch.

PCB LAYOUT CONSIDERATIONS

9.1 Power Supply, Grounding

digital circuitry, may be run from the system logic supply.

place the cap between VBIAS and VA_REF as close to the codec as possible to minimize trace imped- ance
keep the traces for VA and VA_REF separate as much as possible and only connect them at the supply Extensive use of power and ground planes, ground plane fill in unused areas and surface mount decoupling capacitors are recommended. Decoupling capacitors should be as close to the pins of the CS4207 as pos- sible. The low value ceramic capacitor should be closest to the pin and should be mounted on the same side of the board as the CS4207 to minimize inductan ce effects. All signals, especially clocks, should be LINEOUTx + LINEOUTx - - 1000 pF C0G 220 Ω 2.26 kΩ3300 pF C0G 698 Ω 1.5 kΩ4.53 kΩ 2.05 kΩ 1.05 kΩ 22 μF 2200 pF C0G6800 pF C0G 220 pF CS4207 AGND Analog Output 22 μF

kept away from the FILT+ and VCOM pins in order to avoid unwanted coupling into the modulators. The CDB4207 evaluation board demonstrates the optimum layout and power supply arrangements.

9.2 QFN Thermal Pad

The CS4207 is available in a compact QFN package. The underside of the QFN package reveals a large metal pad that serves as a thermal relief to provide for maximum heat dissipation. This pad must mate with an equally dimensioned copper pad on the PCB and must be electrically connected to ground. A series of vias should be used to connect this copper pad to one or more larger ground planes on other PCB layers. In split ground systems, it is recommended that this thermal pad be connected to AGND for best perfor- mance. The CS4207 evaluation board demonstrates the optimum thermal pad and via configuration. 10.PARAMETER DEFINITIONS Dynamic Range The ratio of the rms value of the signal to the rms su m of all other spectral components over the specified bandwidth. Dynamic Range is a signal-to-noise ratio measurement over the specified band width made with a -60 dBFS signal. 60 dB is added to resulting measurement to refer the measurement to full-scale. This technique ensures that the distortion components are below the noise level and do not affect the measure- ment. This measurement te chnique has been accepted by the Au dio Engineering Society, AES17-1991, and the Electronic Industries Association of Japan, EIAJ CP-307. Expressed in decibels. Total Harmonic Distortion + Noise The ratio of the rms value of the signal to the rms su m of all other spectral components over the specified band width (typically 10 Hz to 20 kHz), including di stortion components. Expressed in decibels. Measured at -1 and -20 dBFS as suggested in AES17-1991 Annex A. Frequency Response A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude response at 1 kHz. Units in decibels. Interchannel Isolation A measure of crosstalk between the left and right channel pairs. Measured for each channel at the convert- er's output with no signal to the input under test and a full-scale signal applied to the other channel. Units in decibels. Interchannel Gain Mismatch The gain difference between left and right channel pairs. Units in decibels. Gain Error The deviation from the nominal full-scale analog output for a full-scale digital input. Gain Drift The change in gain value with temperature. Units in ppm/°C. Offset Error
