Overview
MJ1473 Gt~i~~~! ________________________ MJ1473 PCM TRANSMITTER CIRCUIT The MJ1400 Series of circuits have been specifically designed for use in 30 channel PCM systems.
The MJ1473 is designed to simplify the transmit section of a 30 channel, 2 MBit PCM link by converting NRZ PCM data to either AMI or HDB3 format after inserting a synchronising word in channel 0 (conforming to CCITT recommendations G.
703 and G.
732).
The data is output in pseudo-ternary form to facilitate driving the line interface via a transformer and AMI or HDB3 code may be remotely selected using bits 2 and 3 in channel a of the incoming data stream.
FEATURES • 5V - 30mA Power Requirements • 0-70°C Operation • Complies w...
