description
The voice-band audio processor (VBAP) is designed to perform transmit encoding analog/ digital (A/D) conversion, receive decoding digital/analog (D/A) conversion, and transmit and receive filtering for voice-band communications systems. The device operates in either the 15-bit linear or 8-bit companded (µ-law or A-Law) mode, which is selectable through the I 2C interface. The VBAP generates its own internal clocks from a 2.048-MHz master clock input. AVAILABLE OPTIONS TA TQFP PBS PACKAGE PART NO.

An external reset must be applied to the active low RESET terminal to guarantee reset upon power on. After the initial power-on sequence the TWL1103 can be functionally powered up and down by writing to the power control register through the I 2C interface. There is a hardwired selectable power-up terminal in default mode option. The PWRUPSEL function allows the VBAP to power up in the default mode and allows use without a microcontroller. reference A precision band gap reference voltage is generated internally and supplies all required voltage references to operate the transmit and receive channels. The reference system also supplies bias voltage for use with an electret microphone at terminal MBIAS. An external precision resistor is required for reference current setting at terminal REXT. control interface The I 2C interface is a two-wire bidirectional serial interface that controls the VBAP by writing data to the six control registers: /C0068 Power control /C0068 Mode control /C0068 Transmit PGA and sidetone control /C0068 Receive PGA gain and volume control /C0068 DTMF high tone /C0068 DTMF low tone There are two power-up modes which may be selected at the PWRUPSEL terminal: /C0068 The PWRUPSEL state (VDD at terminal 20) causes the device to power up in the default mode when power is applied. In the default mode, the I2C interface is not required, and the device may be used without an I2C interface. The programmable functions are fixed in the default modes. /C0068 The PWRUPSEL state (ground at terminal 20) causes the device to go to a power-down state when power is applied. In this mode an I 2C interface is required to power up the device. phase-locked loop The internal digital filters and modulators require a 10.24-MHz clock that is generated by phase locking to the 2.048-MHz master clock input. PCM interface The PCM interface transmits and receives data at the PCMO and PCMI terminals respectively. The data is transmitted or received at the PCMCLK speed once every PCMSYN cycle. The PCMCLK can be tied directly to the 2.048-MHz master clock (MCLK). The PCMSYN can be driven by an external source or derived from the master clock and used as an interrupt to the host controller. microphone amplifiers The microphone input is a switchable interface for two differential microphone inputs. The first stage is a low- noise differential amplifier that provides a gain of 23.5 dB. The second stage amplifier has a selectable gain of 0 dB or 12 dB.

functional description (continued) analog modulator The transmit channel modulator is a third-order sigma-delta design. transmit filter and PGA The transmit filter is a digital filter designed to meet CCITT G.714 requirements. The device operates in either the 15-bit linear or 8-bit companded µ-law or A-law mode that is selectable through the I2C interface. The transmit PGA defaults to 0 dB. sidetone A portion of the transmitted audio is attenuated and fed back to the receive channel through the sidetone path. The sidetone path defaults to –12 dB. The sidetone path can be enabled by writing to the power control register. receive volume control The receive volume control block acts as an attenuator with a range of –18 dB to 0 dB in 2 dB steps for control of the receive channel volume. The receive volume control gain defaults to 0 dB. receive filter and PGA The receive filter is a digital filter that meets CCITT G.714 requirements with a high-pass filter that is selectable through the I2C interface. The device operates in either the 15-bit linear or 8-bit µ-law or A-law companded mode, which is selectable through the I2C interface. The gain defaults to –1 dB representing a 3-dBm0 level for a 32-Ω load impedance and the corresponding digital full scale PCMI code. The gain may be set to –2 dB for the respective 3-dBm0 level for a 16-Ω load impedance. digital modulator and filter The second-order digital modulator and filter convert the received digital PCM data to the analog output required by the earphone interface. earphone amplifiers The analog signal can be routed to either of two earphone amplifiers, one with differential output (EAR1ON and EAR1OP) and one with single-ended output (EAR2O). Clicks and pops are suppressed for EAR1 differential output only. tone generator The tone generator provides generation of standard DTMF tones and single tone frequencies which are output to the following devices: 1) The buzzer driver, as a pulse density modulation (PDM) signal 2) The receive path digital/analog converter (DAC) for outputting through the earphone. There are 255 possible single tones. The tone integer value is determined by the following formula: Round (Tone Freq (Hz)/7.8135 Hz) The value is loaded into one of two 8-bit registers, the high-tone register (04), or the low-tone register (05). The tone output is 2 dB higher when applied to the high-tone register (04). When generating DTMF tones, the high DTMF tone must be applied to the high-tone register and the low frequency tone to the low-tone register.

VOICE-BAND AUDIO PROCESSOR (VBAP ) SGLS120A – APRIL 2002 – REVISED MAY 2002 25POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PRINCIPLES OF OPERATION DTMF generator operation and interface (continued) Tones from the DTMF generator block are present at all outputs and are controlled by enabling or disabling the individual output ports. The values that determine the tone frequency are loaded into the tone registers (high and lo) as two separate values. The values loaded into the tone registers initiate an iterative table look-up function, placing a 6-bit or 7-bit in twos complement value into the the tone registers. There is a 2 dB difference in the resulting output of the two registers, the high-tone register having the greater result. The resulting range of a tone set into the low register value is +31 {1F}HEX to –32 {20}HEX for a range of six bits and is in twos complement format. The resulting range of a tone set into the high register value is +39 {27}HEX to –40 {D8}HEX in twos-complement format, as well. The maximum range is six bits having a maximum value of {31}HEX. The value {31} is represented as 011111. Two zeros are added to the leading side of the value and then the value is padded with seven LSB zeros to create a value of 000 1111 1000 0000. Because the maximum full scale value is 000 1111 1000 0000, the resulting output magnitude is 20 log (input value/maximum value) or 20 log (3968/16783) or –12.31 dB below full scale. This is the result when all gains are set at default. buzzer logic section The single-ended output BUZZCON is a PDM signal intended to drive a buzzer through an external driver transistor. The PDM begins as a selected tone, is generated and passed through the receive D/A channel, and is fed back to the transmit channel analog modulator, where a PDM signal is generated and routed to the BUZZCON output. support section The clock generator and control circuit uses the master clock input (MCLK) to generate internal clocks to drive internal counters, filters, and converters. Register control data is written into and read back from the VBAP registers via the control interface. I 2C-bus protocols The VBAP serial interface is designed to be I2C bus-compatible and operates in the slave mode. This interface consists of the following terminals: SCL: I2C bus serial clock— This input synchronizes the control data transfer from and to the CODEC. SDA: I2C bus serial address/data input/output— This is a bidirectional terminal that transfers register control addresses and data into and out of the codec. It is an open drain terminal and therefore requires a pullup resistor to V CC (typical 10 kΩ for 100 kHz). TWL1103 has a fixed device select address of {E2}HEX for write mode and {E3}HEX for read mode. For normal data transfer, SDA is allowed to change only when SCL is low. Changes when SCL is high are reserved for indicating the start and stop conditions. Data transfer may be initiated only when the bus is not busy. During data transfer, the data line must remain stable whenever the clock line is at high. Changes in the data line while the clock line is at high are interpreted as a start or stop condition.

Table 10. I2C Bus Conditions A Bus not busy Both data and clock lines remain at high. B Start data transferA high to low transition of the SDA line while the clock (SCL) is high determines a start condition. All commands must proceed from a start condition. C Stop data transfer A low to high transition of the SDA line while the clock (SCL) is high determines a stop condition. All operations must end with a stop condition. for the duration of the high period of the clock signal. Each data transfer is initiated with a start condition and terminated with a stop condition. (microprocessor) must generate an extra clock pulse that is associated with this acknowledge bit. the data line high to enable the master to generate the stop condition. A fixed PCMSYN rate of 8 kHz determines the sampling rate.
