CS8420
13.6.1 Pin Description - Hardware Mode 5
Overall Device Control:
DFC0, DFC1 - Data Flow Control Inputs
DFC0 and DFC1 inputs determine the major data flow options available in Hardware mode, according to
Table
5.
S/AES - Serial Audio or AES3 Input Select
S/AES is connected to DGND in Hardware mode 5, in order to select the AES3 input.
OMCK - Output Section Master Clock Input
Output section master clock input. This pin is not used in this mode and should be connected to DGND.
Audio Output Interface:
SDOUT - Serial Audio Output Port Data Output
Audio data serial output pin. This is also a start-up option pin, and requires a pull-up or pull-down resistor.
OSCLK - Serial Audio Output Port Bit Clock Input or Output
Serial bit clock for audio data on the SDOUT pin.
OLRCK - Serial Audio Output Port Left/Right Clock Input or Output
Word rate clock for the audio data on the SDOUT pin. The frequency will be at the input sample rate (Fsi).
