CXA3250AN

All Band TV Tuner IC with On-chip PLL

For the availability of this product, please contact the sales office.

Description

The CXA3250AN 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.

30 pin SSOP (Plastic)

Features

• 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 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)

Absolute Maximum Ratings (Ta=25 °C)

• CATV tuners

Structure

Bipolar silicon monolithic IC

This IC has the pins whose electrostatic discharge strength is weak as the operating frequency is high and the high-frequency

process is used for this IC.

Take care of handling the IC.
