All Band TV Tuner IC with On-chip PLL
Description The CXA3252N 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 • Superior cross modulation • Supports both IF double-tuned filter and adjacent channel trap.
• 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 high voltage drive transistor for charge pump • Reference frequency selectable from 31.
25, 50 or 62.
