Overview
SC9270 DTMF DEMODULATOR WITH FILTER AND DIGITAL DECODER DESCRIPTION The SC9270C/D 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 and dialtone rejection.
Digital counting techniques are employed in the decoder 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 3-state bus interface.
