CXA3252N Overview
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.
CXA3252N Key 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)
- Low-phase noise synthesizer
- On-chip 4-output band switch (supports output voltages from 5 to 9 V)
- 32 pin SSOP
