M-986-2R2

MFC Transceivers

Description

The M-986-1R2 and -2R2 MFC Transceivers contain

all the logic necessary to transmit and receive CCITT

R2F (forward) and R2B (backward) multifrequency

signals on one 40-pin integrated circuit (IC). M-986-

1R2 is a single-channel version; M-986-2R2 provides

two channels. R1 single and dual multifrequency

transceivers are also available as M-986-1R1 and -

2R1.

Operating with a 20.48 MHz crystal, the M-986 is

capable of providing a direct digital interface to an 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 below.

The M-986 can be configured by the customer to

operate with the transmitter and receiver either cou-

pled together or independently, allowing it to handle a

compelled cycle automatically or via command from

the host processor. For the R2 versions of the M-986,

A-law is used for coding/decoding. The M-986 is con-

figured and controlled through an integral coprocessor

port.
