DTMF TranseiversTheM-8880 is a completeDTMF Transmitter/Receiver that fea-
tures adjustable guard time, Automatic Tone burst mode, call
progressmode, and a fully compatible 6500/6800microproces-
sor Interface The receiver portion is based on the industry stan-
dard M-8870 DTMF Receiver, while the transmitter uses a
switched-capacitor digital-to-analog converter for
low-distortion, highly accurateDTMF signaling. Tone bursts CAN
be transmitted with precise Timing by making use of the auto-
matic Tone burst mode. To analyze call progress Tones a call
progress Filter CAN be selected by an external Microprocessor By Clare, Inc.
