Product Description

The CMD CM8880/8880-2 is a fully integrated DTMF Transceiver, featuring adjustable guard time, automatic tone

burst mode, call progress mode, and a fully compatible 6500/6800 microprocessor interface. The CM8880/8880-2 is

manufactured using state-of-the-art advanced CMOS technology for low power consumption and precise data han-

dling. The CM8880/8880-2 is based on the industry standard CM8870 DTMF Receiver, while the transmitter utilizes a

switched-capacitor D/A converter for low distortion, highly accurate DTMF signaling. Internal counters provide an

automatic tone burst mode which allows tone bursts to be transmitted with precise timing. A call progress filter can

be selected by an external microprocessor for analyzing call progress tones. The CM8880-2 is electrically equivalent to

the CM8880 but does not include the call progress function.
