HC9P55564-5 - Continuously Variable Slope Delta-Modulator (CVSD)

Datasheet Summary

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 conversion is by delta-modulation, using the Continuously Variable Slope (CVSD) method of modulation/demodulation.

Features

  • All Digital.
  • 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.
  • Half Duplex Operation Under Digital Control.
  • Filter Reset Under Digital Control.
  • Automatic Overload Recovery.
  • Automatic “Quiet” Pattern Generation.
  • AGC Control Signal Available.
