Digital Power (Input) - Positive power supply for the digital section. Refer to the Recommended
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.
trates 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.
Control Port Power (Input) - Determines the required signal level for the control port and hard-
ware mode configuration pins. Refer to the Recommended Operating Conditions for appropriate
voltages.
Reset (Input) - The device enters a low power mode and all internal registers are reset to their
default settings when low.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits. Requires the capacitive decoupling to analog ground as shown in the Typical Connection
Diagram.
Quiescent Voltage (Output) - Filter connection for internal quiescent voltage.
Mute Control (Output) - These pins are intended to be used as a control for external mute circuits
on the line outputs to prevent the clicks and pops that can occur in any single supply system.
