CXA3275Q Datasheet | Sony Semiconductor Solutions

PLL/OSC/MIX IC for Digital Tuner Description The CXA3275Q is a monolithic tuner IC for single conversion system digital broadcast tuners. This IC integrates three sets of local oscillator and mixer circuits (VHF Low Band/ VHF High Band/UHF Band), an IF amplifier and a tuning PLL onto a single chip, enabling further miniaturization of the tuner. Features - Balanced oscillators with low-phase noise and excellent oscillation stability (UHF: 4 pins, VHF: 2 pins) - High linearity mixer and IF amplifier - IF output switchable between balanced and unbalanced - Low-phase noise PLL synthesizer (3-wire bus format) - Reference frequency programmable in 4 bits - On-chip high voltage drive transistor for charge pump - On-chip 4-output band switch (PNP transistor on/off) - 40-pin QFP package Applications Digital CATV tuners Structure Bipolar silicon monolithic IC 40 pin QFP...
