Description

The CXA3627N 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 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: 13mA)

? 30-pin SSOP small package

? UHF band switch output switchable
