Interconnections between the DS2152 or DS2154 and the IGT WAC-021-C are shown in Figure 1. Figure 1. Transceiver to WAC-021-C PCM interface. In the circuit shown above the framer outputs a multi-frame synchronization pulse on TSYNC. The signal drivers both TL_FSYNC and TL_MSYNC of the WAC-021-C. TL_FSYNC does not need to be d……
