Xilinx’s Virtex UltraScale devices have achieved compliance to the 25GE, 50GE and 100GE copper cable and backplane IEEE and related specifications which supports up to five metres of copper cabling in the data centre and up to one metre of backplane interconnect. These specifications include the IEEE 802.3bj 100GBASE-CR4/KR4, IEEE 802.3by 25GBASE-CR/CR-S/KR/KR-S, 25 Gigabit Ethernet Consortium 50GBASE-CR2/KR2. Data centre users can now make use of nx25G lanes of copper cabling versus optics for more cost- and power-optimised solutions to connect servers to top-of-rack switches using any off-the-shelf, specification-compliant vendor.
Xilinx transceiver technology delivers, the company asserts, unmatched signal quality and auto-adaptive equalisation to ensure the highest signal integrity and fastest serial link implementation. Along with integrated 100G Ethernet MAC IP, soft error-correction (RS-FEC) IP, and ASIC-class logic fabric, Virtex UltraScale FPGAs provide a complete, high performance and low-latency Ethernet solution for data centre workload acceleration.
