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.
20 pin SSOP (Plastic)
Features
Low power consumption (5 V, 46 mA typ.)
Single 5 V power supply
Superior cross modulation
Balance-type UHF oscillator with good oscillation
stability (4 pins)
IF output can be selected from symmetrical or
asymmetrical
Double-tuned filter can be connected to MIX output
SSOP 20-pin package
