LMH1981 Datasheet (National Semiconductor) - Multi-Format Video Sync Separator

LMH1981, Multi-Format Video Sync Separator

The LMH1981 is a high performance multi-format sync separator ideal for use in a wide range of video applications, such as broadcast and professional video equipment and HDTV/ DTV systems.

The input accepts standard analog video signals with either bi-level or tri-level sync, and the outputs provide

LMH1981 Features

* very low jitter, minimizing external circuitry needed to clean and reduce jitter in subsequent sync processing stages. The LMH1981 automatically detects the input video format, eliminating the need for programming using a microcontroller or external RSET resistor. The sync separator applies precise
