Product details

Description

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.

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 50% sync slicing to ensure accurate sync extraction for inputs with irregular amplitude, offset, and noise conditions. Its unique video format feature (pin 9) outputs the total vertical scan lines per.
