GC4116 MULTI-STANDARD QUAD DUC CHIP
DATA SHEET REV 1.0
Figure 17 illustrates how the resampler section is used with the GC4116. As in the previous configuration, TDM serial data
can be handled by connecting all four resampler serial inputs to the single TDM source and using the RREQ output as the start
of frame signal. In this configuration the resampler outputs drive the channel inputs directly, and the Serial Controller is used to
drive the resampler input timing.
