Product Summary

The HC-55516 is a half duplex modulator/demodulator CMOS intergrated circuit used to convert voice signals into serial NRZ digital data and to reconvert that data into voice. The conversion is by delta-modulation, using the Continuously Variable Slope (CVSD) method of modulation/demodulation. The applications of the HC-55516 include Voice Transmission over Data Channels (Modems), Voice/Data Multiplexing (Pair Gain), Voice Encryption/Scrambling, Voicemail, and Audio Manipulations: Delay Lines, Time Compression, Echo Generation/Suppression, Special Effects, etc. Pagers/Satellites, Data Acquisition Systems, Voice I/O for Digital Systems and Speech Synthesis Requiring Small Size, Low Weight, and Ease of Reprogram ability, Related Literature: AN607, Delta Modulation for Voice Transmission.
