CXA3185/3186N
All Band TV Tuner IC with On-chip PLL
Description
The CXA3185/3186N 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.
