CXA3627N

www.DataSheet4U.com CXA3627N 30 pin SSOP (Plastic) All Band Tuner IC with On-chip PLL 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 Applications TV tuners VCR tuners CATV tuners Structure Bipolar silicon monolithic IC Absolute Maximum Ratings Supply voltage VCC Operating temperature Topr Storage temperature Tstg Allowable power dissipation PD Operating Conditions Supply voltage –0.3 to +5.5 –25 to +75 –55 to +150 580 V °C °C mW VCC 4.75 to 5.30 V Note: This IC has pins whose electrostatic discharge strength is weak as the operating frequency is high and the high-frequency process is used for this IC.
