- AN607, Delta Modulation for Voice Transmission
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 The analog loop filters have been replaced by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.

NOTES:
1. Controlling Dimensions: INCH. In case of conflict between English
and Metric dimensions, the inch dimensions control.
2. Dimensioning and tolerancing per ANSI Y14.5M-1982.
3. Symbols are defined in the “MO Series Symbol List” in Section 2.2 of
Publication No. 95.
4. Dimensions A, A1 and L are measured with the package seated in
JEDEC seating plane gauge GS-3.
5. D, D1, and E1 dimensions do not include mold flash or protrusions.
Mold flash or protrusions shall not exceed 0.010 inch (0.25mm).
6. E and eA are measured with the leads constrained to be perpen-
dicular to datum -C- .
7. eB and eC are measured at the lead tips with the leads unconstrained.
eC must be zero or greater.
8. B1 maximum dimensions do not include dambar protrusions. Dambar
protrusions shall not exceed 0.010 inch (0.25mm).
9. N is the maximum number of terminal positions.
10. Corner leads (1, N, N/2 and N/2 + 1) for E8.3, E16.3, E18.3, E28.3,
E42.6 will have a B1 dimension of 0.030 - 0.045 inch (0.76 -
1.14mm).
