General Description

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 composite 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.

Key Features
