All Band TVTuner IC with On-chip PLL

Description

32 pin SSOP (Plastic)

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.

Absolute Maximum Ratings (Ta=25 °C)

• Supply voltage

VCC1, VCC2−0.3 to + 5.5

VCC3 −0.3 to +10.0

• Balanced UHF oscillator (4 pins) with excellent oscil-

lation stability

• Storage temperature

Tstg

−55 to + 150 °C

• Supports both I²C and 3-wire bus modes

• Automatic identification of 18, 19 or 27-bit control

(during 3-wire bus mode)

• Allowable power dissipation

Operating Conditions

• 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

• Supply voltage

VCC1, VCC2 4.75 to 5.30

VCC3 4.75 to 9.45

• Operating temperature Topr

−25 to +75 °C

580 mW

• On-chip 4-output band switch

(when mounted on a printed circuit board)

(supports output voltages from 5 to 9 V)

• 32 pin SSOP

Applications

• TV tuners

• VCR tuners

• 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.
