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.
Features
Superior cross modulation
Balanced UHF oscillator (4 pins) with excellent
oscillation stability
Supports both I
2
C 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 I
2
C 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)
Applications
TV tuners
VCR tuners
CATV tuners
Structure
Bipolar silicon monolithic IC
All Band TV Tuner IC with On-chip PLL
30 pin SSOP (Plastic)
CXA3250AN
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.
