M-993

Region 1 MF Tone Generator

Description

The M-993 is a monolithic CMOS integrated circuit

designed to generate multifrequency (MF) tone pairs

for use in trunk signaling. The tones generated con-

form to CCITT R1 signal recommendations and to

AT&T MF standards. The M-993 permits design engi-

neers to implement a highly accurate MF sender with

a minimum of space, power, and added components.

The accuracy of the tone frequencies is assured

through use of an easily obtained 3.58 MHz color burst

crystal or an external 3.58 MHz clock source.
