Maxim Integrated Products’ MAX7474 is said to be the industry's first adaptive equalizer for composite video over twisted-pair cables. It automatically compensates for cable losses that occur in the transmission of a composite video signal with blanking and sync (CVBS) over UTP cable lengths of up to 300m, and improves signal quality for cable lengths up to 600m. The device intelligently adapts to cable length and adjusts the video signal gain appropriately, and it automatically switches over to fixed equalization for monochrome CVBS. The MAX7474 is compatible with NTSC and PAL standards.
Any video application that needs to run CVBS over long UTP cables will benefit from this product. Key applications include security video systems, video switching systems, and automotive rear-view cameras.
