CXA3235 Overview
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.
