Sony Semiconductor 

CXA3235/3236N

All Band TV Tuner IC with On-chip PLL

Description

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.

30 pin SSOP (Plastic)

Features

• Low noise figure

• 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

• On-chip 4-output band switch

Applications

• TV tuners

• VCR tuners

• CATV tuners
