Sony Semiconductor 

UHF-Band RF Modulator for VCR

CXA3219M

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.

16 pin SOP (Plastic)

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
