LC7851E - QPSK Demodulation and Audio Signal-Processing IC for Satellite Broadcast Reception

Ordering number : EN5691 CMOS LSI LC7851E QPSK Demodulation and Audio Signal-Processing IC for Satellite Broadcast Reception Overview The LC7851E demodulates the QPSK (quadrature phase shift keying) modulated audio data broadcast by the Japanese BS and CS broadcast satellites and converts that data to an analog audio signal.

This IC integrates on a single chip the audio system signal processing required for BS and CS receivers from QPSK demodulation to analog audio reproduction.

The main func

LC7851E Features

* QPSK demodulator, PCM decoder, digital filters, D/A converters, and operational amplifiers integrated on a single chip.

* The number of required external components has been reduced and adjustment-free operation achieved in the QPSK demodulator by implementing that block as a digit
