- Abstract
- This paper is related to implementing PCB for the high-speed signal of a system interconnection module having 800Gbps bandwidth in a KOSMOS micro-server. We select the Serial RapidIO as the system interconnection network for the KOSMOS micro-server. The bandwidth of an interconnection module, which is communicating with 8 CPUs on two compute cards, is 800Gbps. The module is designed into 12 layers and 14 layers having 1.4T and 1.8T thickness with two different PCB stack-up. The implementation result shows that the high-speed signal integrity placing a signal layer between two power layers has a better quality than placing two signal layers between two power layers.
