Overview

MJ1444 ~~~I~~~!~-------------------------- 2 MBIT PCM SIGNALLING CIRCUIT MJ1444 PCM SYNCHRONISING WORD GENERATOR 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 CCITT recommendations.

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

Relevant inputs and outputs are TTL compatible.
