Description


The GT4123B is a monolithic dual-channel video multiplier for use in a wide range of applications including broadcast and multimedia.

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:
VO = [ ( VC x VA ) + (1 - VC ) x VB ]
where V C is the control input voltage, GT4123B may be varied continuously over the range 0V to 1V, and VA and VB are the video input signals.

The GT4123B is a low power version of the GT4123 and GT4123A Video Multipliers which operates from ± 5V supply voltages and typically draws only 15mA of current.
