The High-speed Reed-Solomon Intel® FPGA IP uses a highly parallel architecture for large applications that require throughput of 100 Gbps and greater. The Physical Coding Sublayer (PCS) is responsible for the encoding of data bits into code groups for transmission via the Physical Medium Attachment (PMA) and the subsequent decoding of these code groups from the PMA. CPU local master - it acts as CPU slave to an external CPU for register access and it also acts as a register bridge. The DesignWare 200G/400G and 800G Ethernet MAC and PCS support IEEE 802.3 and consortium specifications including Reed Solomon Forward Error Correction (FEC) and timestamping with low jitter for maximum precision. A number of GbE packet is measured in the counter by The IEEE classifies the highest correctable rate of these errors in PAM4 optical links as 2.4E-43. National Instruments has partnered with Prentice Hall to bring you large portions of in-depth technical topics from several PTR RF and Communications books, including Digital Communications: Fundamentals and Applications, 2nd Edition. For the OTUCn interface, the FEC is independent from the OTUCn frame so that it can be chosen to be optimized for interface type. 1.5.4.
