Serial audio interface description
Serial audio interface protocols
The STA333W serial audio input was designed to interface with standard digital audio
components and to accept serial data formats. The STA333W always acts as a slave when
receiving audio input from standard digital audio components. Serial data for two channels
is provided using 3 input pins: left/right clock LRCKI (pin 29), serial clock BICKI (pin 28), and
serial data SDI (pin 30).
The available formats are showed in
