LA7780M
QPSK Downconverter for CATV Systems
Overview
The LA7780M is a downconverter for QPSK data demodulation for digital CATV transmission.
This IC integrates a preamplifier, an AGC amplifier, a mixer, an oscillator, a post-amplifier, and other circuits in a single chip, and provides all the functions required from cable signal input through output to the A/D converter.
Functions
• • • • • • • Preamplifier AGC amplifier Mixer Oscillator Post amplifier IF AGC (internal/external) AGC detector
Features
• Since a preamplifier is built in, the LA7780M has adequate sensitivity to handle the input signal from the cable directly.
