MJ1446 2 MBIT PCM SIGNALLING CIRCUIT MJ1446 TIME SLOT 16 RECEIVER AND TRANSMITTER 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.
The MJ1446 has two modes of ope
