Such performance makes the FPGA the only single-chip device for addressing key Nx100G and 400G line card applications and functions. Combined with Xilinx’s leading 100G gearbox, Ethernet MAC, OTN and Interlaken IP, Virtex-7 HT devices provide customers with the levels of system integration they need to meet space, power and cost challenges as they transition to CFP2 optical modules.

Using SSI technology enables Xilinx to deliver not only high-capacity devices built on TSMC’s 28nm high performance/low power process, but also an unprecedented number of transceivers for unmatched system performance. Competing monolithic FPGAs are able to integrate only a fourth of the number of 28 Gbps channels. The heterogeneous implementation of Virtex-7 HT devices also enables the company to make independent technology choices for the core FPGA and 28 Gbps transceiver die, which avoids burdening the FPGA with high leakage transistors that waste system power and bring no benefit to computation tasks. Having 28 Gbps transceivers on silicon separate from the core FPGA fabric further allows for superior noise isolation, enabling best overall signal integrity and system margin, as well as improved productivity for design closure and faster time to market.

In Xilinx’s latest 28 Gbps technology video, a Virtex-7 H580T device demonstrates its abilities to deliver the eye and jitter characteristics needed to reach the performance required to interface to CFP2 optic modules. White papers, videos and more can be found on the company’s 28 Gbps Serial Transceiver Technology page.
