The MT8870D/MT8870D-1 is a complete 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 tonepairs
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.
