Description
The HC-55564 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 conver-
sion is by delta-modulation, using the Continuously Variable
Slope (CVSD) method of modulation/demodulation.
While the signals are compatible with other CVSD circuits, the inter-
nal design is unique. The analog loop filters have been replaced by
very low power digital filters which require no external timing compo-
nents. 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 HC-55564 is usable from 9kbits/s to above 64kbps. See the
Harris Military databook for a MIL-STD-883C compliant CVSD.
Application Note 607.
