... MODEM for Remote Control Systems GENERAL DESCRIPTION The ML7020 is a 1200 bps modem LSI developed for remote control systems. The functions incorporated are those of a 1200 bps FSK modem conforming to ITU-T Recommendations V.23, DTMF signal generation and detection, call progress tone (CPT) generation and detection. Each functional block can be controlled via a 4-bit processor interface ...
