® MT8888C/MT8888C-1 Integrated DTMF Transceiver with Intel Micro Interface Features • • • • • • Central office quality DTMF transmitter/receiver Low power consumption High speed Intel micro interface Adjustable guard time Automatic tone burst mode Call progress tone detection to -30dBm ISSUE 2 May 1995 Ordering MT8888CE/CE-1 MT8888CC/CC-1 MT8888CS/CS-1 MT8888CN/CN-1 Information 20 Pin Plastic DIP 20 Pin Ceramic DIP 20 Pin SOIC 24 Pin SSOP -40°C to +85°C The receiver section is based upon the industry standard MT8870 DTMF receiver while the transmitter utilizes a switched capacitor D/A converter for low distortion, high accuracy DTMF signalling. Internal counters provide a burst mode such that tone bursts can be transmitted with precise timing.
