Description:
The MT8870DE is a complete DTMF receiver integrating both the band-split filter and digital decoder functions. The filter section uses switched capacitor techniques or 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.
