TDM interface specifications

Time-division multiplexing (TDM) is a method of putting multiple data streams in one data signal by separating the

signal into many frames. There are many ways to accomplish this.

TDM interface overview

The block diagram of the TDM interface implemented in the AIS25BA device is illustrated in the following figure.

As depicted in the figure above, the TDM interface is comprised of two control clocks, a frame synchronization

(WCLK) a serial clock (BCLK), and the serial data out (SDOUT).
