6 Synchronous Serial Controller (SSC)

The Synchronous Serial Controller (SSC) is a synchronous communication link that supports several serial protocols generally used in audio and telecom applications, such as I2S, Short Frame Sync and Long Frame Sync.

The SSC contains an independent transmitter and a receiver with a common clock divider. The figure below shows the block diagram of the SSC module.

The transmitter and the receiver consist of three pins each: one data pin (TD for transmitter and RD for receiver), one clock pin (TK for transmitter and RK for receiver) and one frame sync pin (TF for transmitter and RF for receiver).
