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-phas.
