MF Transceiver
Description
The M-986-2A1 dual channel MF Transceiver con-
tains all the logic necessary to transmit and receive
(North American) CCITT Region 1 multifrequency
signals on one integrated circuit (IC).
Operating with a 20.48 MHz crystal, the M-986 is
capable of providing a direct digital interface to a m-
law or A-law encoded PCM digital input. Each channel
can be connected to an analog source using a coder-
decoder (codec) as shown in the Block Diagram
