Codec Serial Audio Data Input (Input) - Input for two's complement serial audio data.
CODEC Serial Clock (Input/Output) - Serial clock for the CODEC serial audio interface.
SCL/CCLK
SDA/CDOUT
AD1/CDIN
Digital Power (Input) - Positive power supply for the digital section.
Digital Ground (Input) - Ground reference. Should be connected to digital ground.
Control Port Power (Input) - Determines the required signal level for the control port.
Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external pull-up
resistor to the logic interface voltage in I2C mode as shown in the Typical Connection Diagram.
Serial Control Data (Input/Output) - SDA is a data I/O line in IC mode and requires an external pull-up
resistor to the logic interface voltage, as shown in the Typical connection Diagram. CDOUT is the output
data line for the control port interface in SPI mode.
Address Bit 1 (I2C)/Serial Control Data (SPI) (Input) - AD1 a chip address pin in I2C mode; CDIN is
the input data line for control port interface in SPI mode.
