Intersil HC3-55536-9
The HC-55536 is a CMOS integrated circuit used to convert serial NRZ digital data to an analog (voice) signal. The analog loop filters have been replaced by digital filters which use very low power and require no external timing components.| Part No. | HC3-55536-9 |

DESCRIPTION
N EW N FOR Conversion is by delta demodulation, using the Continuously Variable Slope (CVSD) method of demodulation. While signals are compatible with other CVSD circuits, the internal design is unique. This digital approach allows inclusion of many desirable features, which otherwise would be difficult to implement. The device is usable from 9Kbits/s to above 64kbits/s, and may be easily configured with the HC-55564 CVSD for a complete transmit/receive voice channel. HC-55536● Low Power Drain: 1.5mW from Single 3V to 6V Supply
● Time Constants Determined by Clock Frequency; No Calibration or Drift Problems; Automatic Offset Adjustment
● Filter Reset by Digital Control
● Automatic Overload Recovery
● Automatic “Quiet” Pattern Generation
APPLICATIONS
● Voice Decoder for Digital Systems and Speech Syntheses● Voicemail
● Audio Manipulations; Delay Lines, Echo Generation/ Suppression, Special Effects, etc.
