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)
• Supply voltage
VCC1, VCC2 –0.3 to +5.5 V
VCC3 –0.3 to +10.0 V
• Storage temperature Tstg –55 to +150 °C
• Allowable power dissipation

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.
