Product Description

The CAMD CM88L70/70C provides full DTMF receiver capability by integrating both the bandsplit filter and digital decoder

functions into a single 18-pin DIP, SOIC, or 20-pin PLCC, TSSOP, or QSOP package. The CM88L70/70C is manufactured using

state-of-the-art CMOS process technology for low power consumption (35mW, max.) and precise data handling. The filter

section uses a switched capacitor technique for both high and low group filters and dial tone rejection. The CM88L70/70C

decoder uses digital counting techniques for the detection and decoding of all 16 DTMF tone pairs into a 4-bit code. This

DTMF receiver minimizes external component count by providing an on-chip differential input amplifier, clock generator, and

a latched three-state interface bus. The on-chip clock generator requires only a low cost TV crystal or ceramic resonator as

an external component.
