TSU 120 User Manual 61202129L1-1

DTE Timing

The DTE is the source of timing. The TSU 120 uses the incom-

ing DTE clock to determine the transmission timing. This is

typically used in applications where it is necessary to have the

DTE as the primary clock source, (such as limited distance line

drivers). See Figure 5-4.
