BNC is a coaxial connector designed to support up to 3Gb/s video transmission. Its performance is primarily determined by the coaxial structure inside the BNC. The transition from the BNC connector to the printed circuit board will heavily influence the performance of the BNC.

A well-designed high-speed PCB layout is not only essential, but also critically important in creating systems that meet SMPTE requirements at 12G-SDI. Passive components pads, BNC landing pads, PCB board material, IC anti-pads, and high-speed routing techniques all have a direct impact on surpassing SMPTE limit requirements.
