Overview: TECHNICAL DATA DTMF RECEIVER High-Performance Silicon-Gate CMOS IL9270 The IL9270N/D is a plete 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 ponent count is minimized by on-chip provision of a differential input amplifier, clock-oscillator and latched 3-state bus interface. • plete receiver in an 18-pin package. • Excellent performance. • CMOS, single 5 volt operation. • Minimum board area. • Central office quality. • Low power consumption.
