Overview
CXA3555N All Band Tuner IC with On-chip PLL 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.
