Mute Control (Output) - The Mute Control pins go high during power-up initialization, reset,
muting, power-down or if the master clock to left/right clock frequency ratio is incorrect.
These pins are intended to be used as a control for external mute circuits to prevent the
clicks and pops that can occur in any single supply system. The use of external mute cir-
cuits are not mandatory but may be desired for designs requiring the absolute minimum in
extraneous clicks and pops.
Differential Analog Output (Output) - The full scale differential analog output level is spec-
ified in the Analog Characteristics specification table.
Analog Power (Input) - Positive power supply for the analog section.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial
audio interface. Refer to the Recommended Operating Conditions for appropriate voltages.
Test - These pins need to be tied to analog ground.
Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an
external pull-up resistor to the logic interface voltage in I
Connection Diagram.
Serial Control Data (Input/Output) - SDA is a data I/O line in I
external pull-up resistor to the logic interface voltage, as shown in the Typical Connection
Diagram. CDIN is the input data line for the control port interface in SPI mode.

Mode Selection (Input) - Determines the operational mode of the device.
DSD Serial Clock (Input) - Serial clock for the Direct Stream Digital audio interface.
DSD-Enable (Input) - When held at logic ‘1’ the device will enter DSD mode (Stand-Alone
mode only).
Direct Stream Digital Input (Input) - Input for Direct Stream Digital serial audio data.
