Functional Description
Strobe Signal
A data strobe signal is generated with every 8-kHz frame. It is active high for a duration
of either 8 or 16 bits (SCFG:TLEN) and its start position is programmable to one of up to
32 channels (SCFG:TSLT) with respect to the FSC signal.
Since the IOM-2 and PCM interface are synchronous in their channel structure, the SDS
signal may be used for external devices connected to either of these interfaces.
Figure 54
Data Strobe Signal Generation
Figure 54 shows two examples for the generation of a strobe signal. In example 1 the
SDS is active during channel B2 on IOM-2 and during channel 1 (C1) on PCM, whereas
in the second example SDS goes high during IC1 and IC2 on IOM-2 and during channel
4 and 5 (C4, C5) on PCM.
