It operates from a 3.3V to 5V supply rail, so it fits into mixed-voltage systems without needing an extra regulator for the sync section. The serial control interface lets a host processor configure the separator's output timing and polarity over a simple two-wire bus, reducing the pin count on the controller side. ## 14-TSSOP surface-mount package It ships in a Tube, so for low-volume builds or prototypes you get the parts in a rigid carrier without the reel handling of tape-and-reel packaging. ## Targeted at professional video equipment Texas Instruments targets the LMH1981MT/NOPB at Professional Video applications — think broadcast cameras, video routers, production switchers, and test equipment that need to recover sync from a composite video feed.","metaTitle":"LMH1981MT/NOPB Texas Instruments Video Sync Separator","metaDescription":"Texas Instruments LMH1981MT/NOPB video sync separator, 3.3V-5V supply, NTSC/PAL, 14-TSSOP.
