LMH1980 Datasheet Auto-detecting Sd/hd/pc Video Sync Separator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: www.DataSheet4U.com July 2007 LMH1980 Auto-Detecting SD/HD/PC Video Sync Separator LMH1980 Auto-Detecting SD/HD/PC Video Sync.

General Description

The LMH1980 is an auto-detecting SD/HD/PC video sync separator ideal for use in a wide range of video applications, such as automotive LCD monitors, video capture & editing devices, surveillance & security equipment, and machine vision and inspection systems.

The LMH1980 accepts an analog video input signal with either bi-level or tri-level sync and automatically detects the video format, eliminating the need for external RSET resistor adjustment required by other sync separators (e.g.: LM1881).

The outputs provide timing signals in CMOS logic, including Composite, Horizontal, and Vertical Syncs, Burst/Back Porch Timing, and Odd/Even Field outputs.

Key Features

  • Analog video sync separation for NTSC, PAL, 480I/P,.
  • 576I/P, 720P, 1080I/P/PsF, and many VESA-compatible timing formats Composite Video (CVBS), S-Video (Y/C), and Component Video (YPBPR/GBR) and PC Graphics (RGsB) interfaces SD/PC Bi-level sync & HD tri-level sync compatible Composite, Horizontal, and Vertical Sync outputs Burst/Back Porch Timing, Odd/Even Field, and HD Detect Flag outputs Automatic video format detection Fixed-level sync slicing fo.
