Dtmf Receiver High-performance Silicon-gate Cmos Corp.

The IN9270 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. 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 Complete receiver in an 18-pin package. Excellent performance. CMOS, single 5 volt operation. Minimum board area. Central office quality. Low power consumption. By Texas Instruments
