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.

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

Applications

• TV tuners

• VCR tuners

• CATV tuners
