Pin Description
1
Digital Interface Signal Level (Input) - Determines the required signal level for the GPIO, S/PDIF and
Digital Mic interfaces. Refer to the Recommended Operating Conditions for appropriate voltages.
2
General Purpose I/O (Input/Output) - General purpose input or output line, or
Digital Mic Data Input (Input) - The second data input line from a digital microphone.
3
Digital Interface Signal Level (Input) - Determines the required signal level for the HD Audio inter-
face. Refer to the Recommended Operating Conditions for appropriate voltages.
4 Digital Mic Clock (Output) - The high speed clock output to the digital microphone.
5 Serial Data Input (Input) - Serial data input stream from the HD Audio Bus.
6 Bit Clock (Input) - 24 MHz bit clock from the HD Audio Bus.
7 Digital Ground (Input) - Ground reference for the internal digital section.
8 Serial Data Output (Input/Output) - Serial data output stream to the HD Audio Bus.
9 Digital Power (Input) - Positive power for the internal digital section.
