Design and characterization of Cell Reference Board with multi-GHz differential channel buses

Higher bandwidth is required to handle a larger volume of information for the high-definition video application in the near future. A multi-GHz differential channel bus on a board must be carefully designed to maintain good eye-diagram with high voltage opening and low timing jitter. Crosstalk noise among differential buses, reflection at the receiver noise, and via discontinuities must be taken into consideration by modeling the interconnections prior to design and fabrication. After being fabricated and assembled, the Cell Reference Board was evaluated in terms of signal integrity, power integrity and EMI
