Xilinx has shipped the Virtex-7 H580T FPGA, which is the first 3D heterogeneous all programmable product. The Virtex-7 H580T features eight 28 Gbps transceivers and plenty of logic capacity. The device is the only FPGA that can integrate additional line card functionality so designers can implement a dual 100G OTN transponder on a single chip.
The Xilinx Virtex-7 HT FPGA uses stacked silicon interconnect (SSI) technology. The device is the industry’s highest bandwidth FPGAs. It features up to sixteen 28 Gbps and seventy-two 13.1 Gbps transceivers. Combined with Xilinx’s 100G gearbox, Ethernet MAC, OTN and Interlaken IP, Virtex-7 HT devices offer engineers the levels of system integration they need to meet space, power and cost challenges as they transition to CFP2 optical modules.The FPGA enables integration capability for communication equipment vendors designing Nx100G and 400G line cards.
Virtex-7 HT devices can support 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. This eliminates 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 16×25 Gbps interfaces. The result is reduced overall power and BOM cost and a more flexible solution in the midst of changing protocols.
The heterogeneous implementation of Virtex-7 HT devices 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 and bring no benefit to computation tasks. The 28 Gbps transceivers on silicon separate from the core FPGA fabric improves noise isolation significantly.
