The end result is that, using Xilinx s stacked silicon interconnect (SSI) technology, heterogeneous Virtex-7 HT devices deliver theindustry s highest bandwidth FPGAs, featuring up to sixteen 28Gbps and seventy-two 13.1 Gbps transceivers, making them the onlysingle-package solutions for addressing key Nx100G and 400G linecard applications and functions. Combined with Xilinx s leading100G gearbox, Ethernet MAC, OTN and Interlaken IP, Virtex-7 HTdevices provide customers with the levels of system integrationthey need to meet space, power and cost challenges as theytransition to CFP2 optical modules. Consider the image below. One of today's Nx100G solutions requiringfive chips can now be implemented using a single Virtex-7 H580T.The result is identical performance with a smaller BOM cost, asignificantly lower power consumption, and improved productivity /reduced time to market.
Using SSI technology enables Xilinx to deliver not onlyhigh-capacity devices built on TSMC s 28nm high performance/lowpower process, but also an unprecedented number of transceivers forunmatched system performance. For example, competing monolithicFPGAs are able to integrate only a fourth of the number of 28 Gbpschannels. The heterogeneous implementation of Virtex-7 HT devices alsoenables Xilinx to make independent technology choices for the coreFPGA and 28 Gbps transceiver die, which avoids burdening the FPGAwith high leakage transistors that waste system power and bring nobenefit to computation tasks. Having 28 Gbps transceivers onsilicon separate from the core FPGA fabric further allows forsuperior noise isolation, enabling best overall signal integrityand system margin, as well as improved productivity for designclosure and faster time to market.
We were impressed by the low transmit jitter of the Virtex-7H580T device s 28 Gbps transceivers and also by how quickly wewere able to bring up a functioning link when combined withLuxtera s 4x28 Gbps single chip silicon photonic transceiver, said Chris Bergey, Vice President of Marketing at siliconphotonics leader Luxtera Inc. Xilinx has clearly hit an industry milestone with this devicebecause it allows makers of networking systems to easily overcomethe challenges they face to enable more bandwidth. Effectively upgrading networks to handle exponential growth in datausage is critical to the communications industry. This requirespower and port density improvements in optical modules whilereducing cost per bit. Driven by the migration to CFP2 and, in thefuture, CFP4 optical modules, Virtex-7 HT devices enableunprecedented integration capability for communication equipmentvendors designing Nx100G and 400G line cards.
With eight 28 Gbps transceivers and ample logic capacity, theVirtex-7 H580T device is the only FPGA that can integrateadditional line card functionality so that designers can implementa dual 100G OTN transponder on a single chip, said Mark Gustlin, System Architect for Wired Communications atXilinx. Competing ASSP-based solutions will comprise five devices, willremain unavailable for more than a year, will consume at least 40percent additional power and will cost 50 percent more. Virtex-7 HT devices with their 28 Gbps transceivers allow supportfor up to four IEEE 100GE gearboxes in a single device with theoption of integrating advanced debug capabilities, OTN, MAC orInterlaken IP within the same FPGA, eliminating the need forseparate gearbox and ASSP devices. The upcoming Virtex-7 H870Tdevice is also 400GE ready and will be able to support future 400GEmodules that require16x25 Gbps interfaces.
The result is reducedoverall power and BOM cost and a more flexible solution in themidst of changing protocols. In Xilinx s newest 28 Gbps technology video , a Virtex-7 H580T device demonstrates its abilities to deliver theeye and jitter characteristics needed to reach the performancerequired to interface to CFP2 optic modules. New white papers , videos and more can be found on Xilinx s 28 Gbps Serial Transceiver Technology page.
