GT4123B Two Channel

Video Multiplier

DATA SHEET

DESCRIPTION

FEATURES

The GT4123B is a monolithic dual-channel video multiplier

for use in a wide range of applications including broadcast

and multimedia.

two-quadrant video multiplication

operation from ±4.5 V to ±13.2 V supply voltages

20 MHz ±0.1 dB video & control channel bandwidth

ultra low differential gain & differential phase

convenient 8 pin package

Featuring two wideband video inputs and a single control

input, the GT4123B achieves broadcast quality mixing of

two video input signals to a single output by implementing

the function:

_O= [ ( V_C• V_A) + (1 - V_C) • V_B]

Pb-free and Green

where V_Cis the control input voltage, which may be varied

continuously over the range 0 V to 1 V, and V_Aand V_Bare

the video input signals.

APPLICATIONS

The GT4123B is a low power version of the GT4123 and

GT4123A Video Multipliers which operates from ±± V

supply voltages and typically draws only 1± mA of current.
