Monolithic Linear IC
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.

Features
鈥?Since a preamplifier is built in, the LA7780M has
adequate sensitivity to handle the input signal from the
cable directly.
(Input signal level:鈥?0 to +30 dBm)
鈥?Both internal and external AGC are supported as the
AGC amplifier drive technique.
鈥?The output amplitude of the post amplifier used to drive
the A/D converter is 2 Vp-p (typical).
鈥?Applications can be designed to use either a crystal or an
inductor oscillator.
