MJ1445 PCM SYNCHRONISING WORD RECEIVER MJ1445 2 MBIT PCM SIGNALLING CIRCUIT The 2.048 Mbit PCM signalling circuits comprise a group of circuits which will perform the common signalling and error detection functions for a 2.048 MBit 30 channel PCM transmission link operating to the appropriate CCITI recommendations.

The circuits are fabricated in N channel metal gate MOS and operate from a single 5volt supply.

Relevant inputs and outputs are TIL compatible.
