Description
The CXA3555N is a monolithic TV tuner IC which integrates local oscillator and mixer circuits for VHF band, local oscillator and mixer circuits for UHF band, an IF amplifier and a tuning PLL onto a single chip, enabling further miniaturization of the tuner.

Features
• Low power consumption (5V, 63mA typ.)
• Low noise figure, low distortion characteristics
• High gain/low gain selectable
• Supports IF double-tuned/adjacent channel trap
• Balanced oscillator circuits (3 sets) with excellent oscillation stability
• On-chip PLL supports I2C bus
• On-chip high voltage drive transistor for charge pump
• Frequency step selectable from 31.25, 50 or 62.5kHz (when using a 4MHz crystal)
• Low-phase noise synthesizer
• On-chip 4-output band switch (output voltage: 5V, current capacity: 5mA)
• 30-pin SSOP small package

Applications
• TV tuners
• VCR tuners
• CATV tuners
