Serial audio interface protocols

The STA380WS serial audio input was designed to interface with standard digital audio

components and to accept serial data formats. The STA380WS 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 shown in Table 7 and Table 8, and set through Configuration
