Product
The CAMD CM8888/8888-2 is a fully integrated DTMF Transceiver, featuring adjustable guard time, automatic tone burst
mode, call progress mode, and a fully compatible 8051, 8086/8 microprocessor interface. The CM8888/8888-2 is
manufactured using state-of-the-art advanced CMOS technology for low power consumption and precise data handling.
The CM8888/8888-2 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 CM8888-2 is electrically equivalent to the CM8888 but does
not include the call progress function.
