MJ1440 2 MBIT PCM SIGNALLING CIRCUIT MJ1440 HDB3 ENCODER/DECODER 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 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.
The MJ 1440 is an encoder/decoder for the pseudoternary tr
