Pin Description
Digital Power (Input) - Positive power supply for the digital section. Refer to the Recom-
mended Operating Conditions for appropriate voltages.
Ground (Input) - Ground reference. Should be connected to analog ground.
Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters. Table 5
illustrates several standard audio sample rates and the required master clock frequencies.
Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the
serial audio data line. The frequency of the left/right clock must be at the audio sample rate, Fs.
Serial Data Input (Input) - Input for two’s complement serial audio data.
Serial Clock (Input) - Serial clocks for the serial audio interface.
Test - These pins need to be tied to analog ground.
Reset (Input) - The device enters a low power mode and all internal registers are reset to their
default settings when low.
Analog Power (Input) - Positive power supply for the analog section. Refer to the Recom-
mended Operating Conditions for appropriate voltages.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio
interface. Refer to the Recommended Operating Conditions for appropriate voltages.
Control Port Power (Input) - Determines the required signal level for the control port and stand
alone configuration pins. Refer to the Recommended Operating Conditions for appropriate volt-
ages.
