May 30, 2012 -- Xilinx Inc. today announced initial shipments of the Virtex-7 H580T FPGA, the first 3D heterogeneous all-programmable product. Virtex-7 HT devices use Xilinx's stacked-silicon interconnect (SSI) technology to deliver the industry's highest bandwidth FPGAs, featuring up to sixteen 28-Gbps and seventy-two 13.1-Gbps transceivers, making them the only single-chip solutions for addressing key Nx100G and 400G line card applications and functions. Combined with Xilinx's 100G gearbox, Ethernet MAC, OTN and Interlaken IP, Virtex-7 HT devices provide developers 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 28-nm high-performance/ ow-power process, but also an unprecedented number of transceivers for unmatched system performance. Other 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 Xilinx 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. 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.

"We were impressed by the low transmit jitter of the Virtex-7 H580T device's 28-Gbps transceivers and also by how quickly we were able to bring up a functioning link when combined with Luxtera's 4x28-Gbps single-chip silicon photonic transceiver," said Chris Bergey, Vice President of Marketing at Luxtera, Inc. "Xilinx has clearly hit an industry milestone with this device because it allows makers of networking systems to easily overcome the challenges they face to enable more bandwidth."

Effectively upgrading networks to handle exponential growth in data usage is critical to the communications industry. This requires power and port-density improvements in optical modules while reducing cost per bit. Driven by the migration to CFP2 and, in the future, CFP4 optical modules, Virtex-7 HT devices enable unprecedented integration capability for communication equipment vendors designing Nx100G and 400G line cards.

"With eight 28-Gbps transceivers and ample logic capacity, the Virtex-7 H580T device is the only FPGA that can integrate additional line card functionality so that designers can implement a dual 100G OTN transponder on a single chip," said Mark Gustlin, System Architect for Wired Communications at Xilinx. "Competing ASSP-based solutions will comprise five devices, will remain unavailable for more than a year, will consume at least 40 percent additional power and will cost 50 percent more."

Virtex-7 HT devices with their 28-Gbps transceivers allow support for up to four IEEE 100GE gearboxes in a single device with the option of integrating advanced debug capabilities, OTN, MAC or Interlaken IP within the same FPGA, eliminating the need for separate gearbox and ASSP devices. The upcoming Virtex-7 H870T device is also 400GE ready and will be able to support future 400GE modules that require 16x25-Gbps interfaces. The result is reduced overall power and BoM cost and a more-flexible solution in the midst of changing protocols.

Availability

First silicon FPGAs are shipping to key customers today with development tool support available in the recently announced Vivado Design Suite.
