Abstract
This paper presents a high speed digital video display interface system implemented with 0.5~ CMOS technology, which can overcome the EM1 and power bottlenecks in the high resolution flat panel display systems. The proposed interface system enables high speed (up to 800 Mbps) low voltage swing serial data transmission which drastically cuts the number of parallel lines down to 4 pairs and reduces EM1 effects in the video data transmission. A newly proposed transition controlled coding scheme minimizes the number of transitions on the serial data stream down to 22% per byte. The high speed low voltage swing serial interface using proposed digital PLL and the transition controlled coding scheme supports resolutions beyond XGA (1 024 X 768) without the EM1 and power problem.
