GT4123B Two Channel Video Multiplier DATA SHEET FEATURES 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 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 VA ) + (1 - VC ) VB ] where VC is the control input voltage, which may be varied continuously over the range 0 V to 1 V, 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 ± 5 V supply voltages and typically draws only 15 mA of current.
