GS4981 Overview
The GS1881, GS4881 and GS4981 are general purpose sync separators for use in a wide variety of video applications. The devices extract the timing information from posite video signals with scan rates from 15 to 130kHz. The GS1881 is a drop-in replacement for the industry standard LM1881 with much improved performance.
