CXA3219M
UHF-Band RF Modulator for VCR
Description The CXA3219M is a UHF-band RF modulator which converts the frequency of audio and video signals. Some circuits which comprise this IC are a UHF oscillator video clamp, white clip, video modulator, audio FM modulator and an intercarrier SW. Features Low voltage of 5V Wide bandwidth 470 to 750MHz UHF oscillator greatly reduces external parts Sharp white clip circuit Built-in voltage
regulator can accept large fluctuation of supply voltage Video input of 0.5Vp-p for general-purpose use Mixer simplifies RF unit design Picture/sound ratio is adjustable with external parts Intercarrier switch Structure Bipolar silicon monolithic IC Block Diagram and Pin Configuration
