Figure 16 illustrates how to use the GC4116 without the Resampler. The Serial Controller generates the serial clock and
frame strobes used to clock the data out of the user’s data source ASIC or DSP chip. This configuration guarantees that the data
will be received by the GC4116 at the correct times. If a serial TDM bus is used as the data source, then the single serial data
source is connected to all four serial inputs of the GC4116 chip, and the CHREQ output from the GC4116 chip is used as the
frame start signal to the data source chip. The four serial frame strobes are used by the GC4116 chip to identify the appropriate
time slots within the TDM stream.
