SC9270D DTMF Receiver

SC9270D DTMF Receiver

SC9270D is complete DTMF receiver integrating both the bandsplit filter and digital decoder functions.Filter section uses switched capacitor techniques for high- and low-group filters and dial-tone 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.
