Functions listed by pin number 1. 8kHz BkHz square wave output. 2. 16kHz 16 kHz square wave output. 3. Clock System clock input (2.048 MHz for a 2Mbit PCM system) 4. Alarm inhibit A high level on this input inhibits the BkHz timing signal on the AMi clock outputs. 5. AMI output Alternative Mark Inve.

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.
