9 Detailed Description
9.1 Overview
The integrated PLL on the device provided adds the flexibility to remove the system clock (commonly known as master clock), allowing a 3-wire I2S connection and reducing system EMI. Powersense undervoltage protection utilizes a two-level mute system. Upon clock error or system power failure, the device digitally attenuates the data (or last known good data) and then mutes the analog circuit. Compared with existing DAC technology, the PCM510xA devices offer up to 20 dB lower out-of-band noise, reducing EMI and aliasing in downstream amplifiers/ADCs. (from traditional 100-kHz OBN measurements to 3 MHz). The PCM510xA devices accept industry-standard audio data formats with 16- to 32-bit data. Sample rates up to 384 kHz are supported.

Sampling frequency is symbolized by fS. Full scale is symbolized by FS. Sample time as a unit is symbolized by tS.
9.3.2 Audio Data Interface
9.3.2.1 Audio Serial Interface
The audio interface port is a 3-wire serial port with the signals LRCK, BCK, and DIN. BCK is the serial audio bit clock, used to clock the serial data present on DIN into the serial shift register of the audio interface. Serial data is clocked into the PCM510xA on the rising edge of BCK. LRCK is the serial audio left/right word clock. LRCK polarity for left/right is given by the format selected.

11.3 External Power Sense Undervoltage Protection Mode
- If the XSMT pin makes a transition from “1”to “0”over 6 ms or more, the device switches into external under- voltage protection mode. This mode uses two trigger levels: – When the XSMT pin level reaches 2 V, soft mute process begins. – When the XSMT pin level reaches 1.2 V, analog mute engages, regardless of digital audio level, and analog shutdown begins. (DAC and related circuitry powers down). If XSMT is moved from "1" to "0" in 20 ns or less, then the device will interpret it as a digital controlled request to mute. It will perform a soft mute, then move to standby. A timing diagram to show this is shown in Figure 40. NOTE The XSMT input pin voltage range is from –0.3 V to DVDD+0.3 V. The ratio of external resistors must produce a voltage within this input range. Any increase in power supply (such as power supply positive noise or ripple) can pull the XSMT pin higher than DVDD+0.3 V. For example, if the PCM510xA is monitoring a 12-V input, and dividing the voltage by 4, then the voltage at XSMT during ideal power supply conditions is 3.3 V. A voltage spike higher than 14.4 V causes a voltage greater than 3.6 V (DVDD+0.3) on the XSMT pin, potentially damaging the device. Providing the divider is set appropriately, any DC voltage can be monitored.

11.5 PCM510xA Power Modes
11.5.1 Setting Digital Power Supplies and I/O Voltage Rails
The internal digital core of the PCM510xA devices run from a 1.8-V supply. This can be generated by the internal LDO, or by an external 1.8-V supply. DVDD is used to set the I/O voltage, and to be used as the input to the onchip LDO that creates the 1.8 V required by the digital core. For systems that require 3.3 V I/O support, but lower power consumption, DVDD should be connected to 3.3 V and LDOO can be connected to an external 1.8-V source. Doing so will disable the onchip LDO. When setting I/O voltage to be 1.8 V, both DVDD and LDOO must be provided with an external 1.8-V supply.
11.5.2 Power Save Modes
The PCM510xA devices offer two power-save modes: standby and power-down. When a clock error (SCK, BCK, and LRCK) or clock halt is detected, the PCM510xA device automatically enters standby mode. The DAC and line driver are also powered down. When BCK and LRCK remain at a low level for more than 1 second, the PCM510xA device automatically enters powerdown mode. Power-down mode disables the negative charge pump and bias/reference circuit, in addition to those disabled in standby mode. When expected audio clocks (SCK, BCK, LRCK) are applied to the PCM510xA device, or if BCK and LRCK start correctly while SCK remains at ground level for 16 successive LRCK periods, the device starts its powerup sequence automatically.

12 Layout
12.1 Layout Guidelines
- The PCM510xA family of devices are simple to layout. Most engineers use a shared common ground for an entire device. GND can be consider AGND and DGND connected.
- Good system partitioning should keep digital clock and interface traces away from the analog outputs for highest analog performance. This reduces any high speed clock return currents influencing the analog outputs.
- Power supply and charge pump decoupling capacitors should be placed as close as possible to the device.
- The top layer should be used for routing signals, whilst the bottom layer can be used for GND.
