The MAX7474 adaptive equalizer recovers losses incurred in the transmission of a composite video (CVBS) signal over unshielded twisted-pair (UTP) cable. The device fully recovers losses for cable lengths of up to 300m and greatly improves signal quality for cable lengths of up to 600m. The device automatically adapts to all cable lengths for CVBS signals with color burst and allows fixed-equalization settings for video signals without burst. The MAX7474 is optimized to provide compensation for losses that occur when transmitting composite video signals over UTP cables such as Category 5e. The device compensates for low frequency and chroma band losses. The MAX7474 is compatible with NTSC and PAL standards.
The MAX7474 accepts differential input and provides a single-ended output. The output is capable of driving two AC- or DC-coupled standard 150Ω video loads. The output back-porch DC level is adjustable with an externally applied DC voltage at the BPLVL input. The device also features loss-of-sync (LOS) and loss-of-burst (LOB) logic outputs.
The MAX7474 is available in a 16-pin SSOP package and is fully specified over the extended (-40°C to +85°C) temperature range.
