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 sin-
gle supply system. The use of external mute circuits 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 specified in the
Analog Characteristics specification table.
Analog Power (Input) - Positive power supply for the analog section. Refer to the Recommended Oper-
ating Conditions for appropriate voltages.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio inter-
face. Refer to the Recommended Operating Conditions for appropriate voltages.
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
Serial Control Data (Input/Output) - SDA is a data I/O line in I
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.
Address Bit 0 (I
CS is the chip select signal for SPI format.
Mode Selection (Input) - Determines the operational mode of the device as detailed in Tables 6 and 7.
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.
