HSP50306 Datasheet (Intersil Corporation)

HSP50306, Digital QPSK Demodulator

The HSP50306 is a 6-bit QPSK demodulator chip designed for use in high signal to noise environments which have some multipath distortion.

The part recovers 2.048 MBPS data from samples of a QPSK modulated 10.7MHz or 2.1MHz carrier.

The chip coherently demodulates the waveform, recovers symbol timing
