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 62.5 kHz (when using a 4 MHz crystal).
- Lo.
