Dual Tone Multiple Frequency
Line Interface
The MC145740 is a silicon gate HCMOS LSI designed for general purpose
Dual Tone Multiple Frequency (DTMF) communications, and contains a DTMF
signal generator and a receiver for all 16 standard digits.
The generator block has a differential line driver which drives a 600
鈩?/div>
load
with 0 dBm level. The transmit signal level is adjusted in 1 dB steps by the
programmable attenuator.
The receiver block has an Auto Gain Control (AGC) amplifier to demodulate
50 dB (typ) dynamic range of DTMF signals to the hexadecimal codes.
The device also includes a serial control interface that permits a CPU to
exercise the following built鈥搃n features.
