CS9370 - DTMF Receiver

Datasheet Summary

Description

The CS9370 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 dial-tone rejection.

The 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 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.
