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.
