Abstract:The CXA3275Q is a monolithic tuner IC for singleconversion system digital broadcast tuners. This ICintegrates three sets of local oscillator and mixercircuits (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 This IC has pins whose electrostatic discharge strength is weak as a high-frequency process is used for this IC。Supply voltage Vcc, PLLVcc 4.5 to 5.5 V ,IFVcc 4.5 to 5.5V,Operating temperatureTopr –40 to +80 °C
