CXA3235/3236N

All Band TV Tuner IC with On-chip PLL

Description

30 pin SSOP (Plastic)

The CXA3235/3236N 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.

The PLL on this IC supports the I²C bus format.

Features

• Low noise figure

Absolute Maximum Ratings (Ta = 25 °C)

• Low power consumption (5 V, 54 mA typ.)

• On-chip tuning PLL (I²C bus format)

• Selection of frequency steps 31.25 kHz, 50 kHz

and 62.5 kHz

• Supply voltage VCC1,VCC2

–0.3 to +5.5

VCC3

–0.3 to +10.0

• Storage temperature

Tstg

• Allowable power dissipation

–55 to +150

880

°C

• On-chip 4-output band switch

Applications

• TV tuners

(when mounted on a substrate)

• VCR tuners

• CATV tuners

Operating Conditions

• Supply voltage VCC1, VCC2 4.75 to 5.30

VCC3

4.75 to 9.45

Structure

• Operating temperature

Topr

Bipolar silicon monolithic IC

–25 to +75

°C

Note) Electrostatic discharge strength is weak, and care should be taken in handling this IC.
