CXA1665AM/AM-S
All Band TV Tuner IC (VHF-CATV-UHF)
Description
The CXA1665AM/AM-S is a single chip TV tuner
IC which performs as an oscillator, mixer for
VHF/CATV and UHF bands. An IF amplifier is also
provided.
This IC adopts a 16-pin SOP package in response
to the trend toward miniaturizing the tuner and
automatic IC mounting. This IC achieves a large
reduction of external parts in addition to
miniaturizing the tuner and increasing manufacturing
productivity, reliability and design efficiency.
