Sony Semiconductor 

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.
