HC-55564/883
FN3738.1
Continuously Variable Slope
Delta-Modulator (CVSD)
The HC-55564/883 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.
While the signals are compatible with other CVSD circuits,
the internal design is unique. The analog loop filters have
been replaced by very low power digital filters which require
no external timing components. This approach allows
inclusion of many desirable features which would be difficult
to implement using other approaches.
The fundamental advantages of delta-modulation, along with
its simplicity and serial data format, provide an efficient (low
data rate/low memory requirements) method for voice
digitization. The device may be easily configured with the
National TP3040 PCM/CVSD filter.
The HC-55564/883 is usable from 9k bits/sec to above
64kbps. For more applications information, see Application
Notes AN576 and AN607.
