Abstract
In order to transmit the long-distance HD video with twisted pair cable, a long-distance transmission system of VGA analog differential signal is designed and the circuits are completed. The signal is driven by AD8147 chip on the sending side and is restored by AD8123 chip through balancing and compensating on the receiving end. The experiments show that, the system is able to transmit 720P HD video with no distortion using maximum 300 meters CAT-5e twisted pair cable. The video image is clear and the color is full after transmission.
