Low Bit Rate Voiceband Encoders/Decoders Semiconductor March 1993 Features • All Digital • Requires Few External Parts D E D EN Continuously Variable Slope M M S O N Delta-Demodulator (CVSD) C G I E S E TR D O Description N EW N FOR The HC-55536 is a CMOS integrated circuit used to convert serial NRZ digital data to an analog (voice) signal.
Conversion is by delta demodulation, using the Continuously Variable Slope (CVSD) method of demodulation.
While signals are compatible with other CVSD circuits, the internal design is unique.
The analog loop filters have been replaced by digital filters which use very low power and require no external timing components.
This digital approach allows inclusion of many desirable features, which otherwise would be difficult to implement.
The device is usable from 9Kbits/s to above 64kbits/s, and may be easily configured with the HC-55564 CVSD for a complete transmit/receive voice channel.
