MJ1440 Description
MJ1440 2 MBIT PCM SIGNALLING CIRCUIT MJ1440 HDB3 ENCODER/DECODER The 2.048 MBit PCM Signalling Circuits prise a group of circuits which will perform the mon signalling and error detection functions for a 2.048 MBit PCM transmission link operating to the appropriate CCITT remendations. The circuits are fabricated in N-channel metal gate MOS and operate from a single 5 volt supply, relevant inputs and outputs are TTL...
