Serial Control Data (Input/Output) - Bi-directional data I/O for the I²C control port.
Serial Data Input (Input) - Input channels serial audio data.
Frame Synchronization Clock/Left/Right Clock (Input/Output) - Determines which channel or
frame is currently active on the serial audio data line.
Master Clock (Input) -Clock source for the internal logic, processing, and modulators.
Serial Clock (Input/Output) -Serial Clock for the serial data port.
Serial Data Output 1 (Output) - ADC data output into a multi-slot TDM stream or AIN1 and AIN2
ADC data output in Left Justified and I²S modes.
Interface Power (Input) - Positive power for the digital interface level shifters.
Ground (Input) - Ground reference for the I/O and digital, analog sections.
