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)
