Description
The MT88L70 is a complete 3 Volt, DTMF receiver
integrating both the bandsplit filter and digital decoder
functions. The filter section uses switched capacitor
techniques for high and low group filters; the decoder
uses
digital counting techniques to detect and decode
all 16 DTMF tone-pairs into a 4-bit code. External
component count is minimized by on chip provision of
a differential input amplifier, clock oscillator and latched
three-state bus interface.
