3G: The Evolution of the Serial Digital Interface (SDI)
SMPTE and the International Telecommunications Union (ITU) have both recently adopted new standards for a 3-Gbit/sec (nominal) SDI interface using 75Ω coaxial cable and BNC connectors. The interest in these interfaces is driven by a desire to be able to transport 1080-line progressive format video over a single-link interface, rather than the dual-link interfaces currently used. The implementation of this interface with existing infrastructure components such as patch panels, connectors, coax cable types, and such, has been studied, and key components have been realized in silicon. The results of this work and key design guidelines are discussed in this paper.
