CXA3250N Datasheet | Sony Semiconductor Solutions

All Band TV Tuner IC with On-chip PLL Description The CXA3250N 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 (5 V, 69 m A typ.) - Superior cross modulation - Balanced UHF oscillator (4 pins) with excellent oscillation stability - Supports both I2C and 3-wire bus modes - Automatic identification of 18, 19 or 27-bit control (during 3-wire bus mode) - On-chip A/D converter (during I2C bus mode) - On-chip high voltage drive transistor for charge pump - Reference frequency selectable from 31.25, 50 or 62.5 k Hz (when using a 4 MHz crystal) - Low-phase noise synthesizer - On-chip 4-output band switch (supports output voltages from 5 to 9 V) Applications - TV tuners - VCR tuners - CATV tuners Structure Bipolar silicon monolithic IC 30 pin SSOP...
