High-Speed Board Layout Challenges in FPGA/SDI Sub-Systems

Wed, 18 Nov 2009 15:37:00 EST

Many video systems are implemented with feature-rich FPGA and multi-rate SDI integrated circuits that support high performance professional video transport over long distances. But FPGAs demand high density routing with fine trace width while high-speed analog SDI routing demands impedance matching and signal fidelity. This paper outlines the layout challenges facing hardware engineers and provides recommendations for dealing with these challenges.
