Serial audio output interface format: determines the
interface format of the output serial digital audio
interface.
The STA308A features a serial audio output interface that consists of 8 channels. The serial
audio output always acts as a slave to the serial audio input interface and, therefore, all
output clocks are synchronous with the input clocks. The output sample frequency (fs) is
also equivalent to the input sample frequency. In the case of SACD/DSD input, the serial
audio output acts as a master with an output sampling frequency of 176.4 kHz. The output
serial format can be selected independently from the input format and is done via the SAO
and SAOFB bits.
