Description

This is Adaptive Equalizer. 19-3216; Rev 0; 1, 08 KIT ATION EVALU E L B AVAILA Adaptive Equalizer for Video Over Twisted Pair General Description Features Automatically Equalizes Up to 600m (Fully Recovers Losses Up to 300m) of UTP Cable Carrying CVBS Automatic Switchover to Fixed Equalization for CVBS Without Color Burst Integrated Video Driver with Adjustable Back-Porch Clamp Level LOS and LOB Output NTSC and PAL Compatible 16-Pin SSOP Package MAX7474 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 sig.
