Description
The HC-55536 is a CMOS integrated circuit used to convert
serial NRZ digital data to an analog (voice) signal. Conver-
sion 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 The analog loop filters have been
replaced by digital filters which use very low power and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.
