Serial Sound Interface
Serial Sound Interface is a synchronous serial data interface used primarily for transferring digital audio data. This
functional block is compatible with the I
A channel is any single output of an audio system. For example, the left and right speakers are the two channels of a
simple stereo audio system. The bus has 4 lines:
• Continuous serial clock (SCK);
• Word (channel) select (WS);
• Serial data out (XMT);
• Serial data in (RX).
The channel being transmitted changes on every transition of WS. A Serial Sound Interface-based communication
system has two Serial Sound Interfaces and a master controller which generates both SCK and WS. A Serial Sound
Interface which generates the controls (SCK and WS) along with its transmit and receive signals is operating as a
master. A Serial Sound Interface which uses external control signals is operating as a slave. The Serial Sound
Interface on this device operates only as a slave.
Figure 1.115 shows a high level system diagram of a Serial Sound Interface setup and its associated waveforms
when configured for six channels.
