CXA3275Q 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.
