Overview

DESCRIPTION The 75T204 is a complete Dual-Tone Multifrequency (DTMF) receiver that detects 16 standard digits.
No front-end pre-filtering is needed.
The only external components required are an inexpensive 3.
58-MHz television “colorburst” crystal for frequency reference and a bias resistor.
An Alternate Time Base (ATB) is provided to permit operation of up to 10 75T204's from a single crystal.
The 75T204 employs state-of- the-art "switched-capacitor" filter technology, resulting in approximately 40 poles of filtering, and digital circuitry on the same CMOS chip.
The analog input signal is pre-processed by 60-Hz reject and band split filters and then zero-cross detected to provi...
