GT4123B Overview
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 VA ) + (1 - VC ) VB ] where VC is the control input voltage, which may be varied...
