HC-55564

Continuously Variable

Slope Delta-Modulator (CVSD)

February 1999

Features

Description

• All Digital

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.

• Requires Few External Parts

• Low Power Drain: 1.5mW Typical From Single 4.5V

To 6V Supply

• Time Constants Determined by Clock Frequency;

No Calibration or Drift Problems: Automatic Offset

Adjustment

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 The analog loop filters have been replaced by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.

• Half Duplex Operation Under Digital Control

• Filter Reset Under Digital Control

• Automatic Overload Recovery

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.

• Automatic “Quiet” Pattern Generation

• AGC Control Signal Available

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.

Applications

• Voice Transmission Over Data Channels (Modems)

• Voice/Data Multiplexing (Pair Gain)

• Voice Encryption/Scrambling

• Voicemail
