Two Channel Video Multipliers

DATA SHEET

FEATURES

DESCRIPTION

The GT4123 and GT4123A are monolithic dual-channel

video multipliers for use in a wide range of applications

including broadcast and multimedia.

• two-quadrant video multiplication

• 20 MHz 0.1 dB video & control channel bandwidth

• one external frequency compensation adjustment

• ultra low differential gain & differential phase

• convenient 8 pin package

Featuring two wideband video inputs and a single control

input, they achieve high quality video mixing of the two

video input signals to a single output by implementing the

function:

V_O= [ ( V_C• V_A) + (1 - V_C) • V_B]

where V_Cis the control input voltage, which may be varied

continuously over the range 0 to 1V with respect to the

ground pin, and V_Aand V_Bare the video input signals.

APPLICATIONS

• Multimedia Graphics Overlay

• Production switchers

• Linear Keyers

The GT4123 operates with typical power supply voltages

of ±10 volts and draws 15 mA of current. The GT4123A

typically operates from +12 and -5 volt supplies. Both are

available in 8 pin PDIP and 8 pin SOIC.
