DTMF RECEIVER

High-Performance Silicon-Gate CMOS

The KK9270N/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 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.
