Description
The M-8888 is a complete DTMF Transmitter
Receiver that features adjustable guard time, auto-
matic tone burst mode, call progress mode, and a fully
compatible 8051, 8086/8 microprocessor interface.
The receiver portion is based on the industry standard
M-8870 DTMF Receiver, while the transmitter uses a
switched-capacitor digital-to-analog converter for low-
distortion, highly accurate DTMF signaling. Tone
bursts can be transmitted with precise timing by mak-
ing use of the automatic tone burst mode. To analyze
call progress tones, a call progress filter can be select-
ed by an external microprocessor.
