HC-55536 Overview
N EW N FOR The HC-55536 is a CMOS integrated circuit used to convert serial NRZ digital data to an analog (voice) signal. Conversion is by delta demodulation, using the Continuously Variable Slope (CVSD) method of demodulation. While signals are patible with other CVSD circuits, the internal design is unique.
