Equalizer compensates for cable losses during video transmission

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX7474, an adaptive equalizer for composite video over twisted-pair cables.

The MAX7474 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. The MAX7474 also 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.

The MAX7474 is intended for any video application that needs to run CVBS over long UTP cables. Key applications include security video systems, video switching systems, and automotive rear-view cameras.

Pricing: Starts at $6 (1000-up, FOB USA).

Availability: Samples and evaluation kits are available.
