CXA3225N
All Band TV Tuner IC (VHF-CATV-UHF)
Description
The CXA3225N is a TV tuner monolithic IC which
integrates local oscillator and mixer circuits for VHF
band, local oscillator and mixer circuits for UHF
band, and an IF amplifier onto a single chip. This IC
adopts a 20-pin SSOP package and is suitable for
miniaturizing voltage synthesizer tuner.
