Xilinx Introduces Versatile Telecom Accelerator Cards for Growing 5G O-RAN Virtual Baseband Unit Market

September 16, 2020, Beijing, China – Xilinx, Inc. (NASDAQ: XLNX), the global leader in adaptive and intelligent computing, today announced that it is targeting O-RAN distributed units in 5G networks. (O-DU) and Virtual Baseband Unit (vBBU) launched the T1 Telecom Accelerator Card. Developed using field-proven Xilinx silicon and IP that is being widely deployed in 5G networks, the accelerator card is the industry’s only multi-function PCIe capable of running both O-RAN fronthaul protocols and L1 offload capabilities A “2-in-1” board with a size specification. With its own advanced offload capabilities, the T1 card drastically reduces the number of CPU cores required by previous systems. Compared with other competing solutions, the T1 card can not only reduce the total system power consumption and cost, but also support O-DU to provide better 5G performance and services.

The O-DU and vBBU solutions provide an open and standard platform for a wide range of 5G virtualization services, which are rapidly growing in demand in the market. The T1 card is a small form factor, single-slot board that can be plugged into standard x86 or non-x86 servers to achieve the real-time protocol processing performance required by 5G virtualized O-DU platforms. In addition, the card offloads line-rate and compute-intensive functions including channel encoding/decoding using hardened LDPC and Turbo codecs, rate-matching/de-matching, HARQ buffer management, etc., which help free up processor core usage. It focuses on running other businesses and is truly virtualized. The T1 card provides “turnkey solutions” through ecosystem partners, including O-RAN fronthaul reference designs and 5G NR L1 reference designs, as well as pre-validated software that simplifies 5G deployment and can help operators, system integration Manufacturers and OEMs quickly enter the market.

Offloading critical channel encoding functions from the CPU to the T1 card can increase codec throughput by 45x and 23x, respectively, compared to the server implementation before acceleration. At the same time, T1 cards can greatly reduce system cost and total power consumption by helping to occupy fewer CPU cores. Additionally, for O-RAN fronthaul termination, the board can handle multiple sectors of 5G NR 4TRX with 100MHz occupied bandwidth (OBW) through its 50Gbps optical port. Fronthaul bandwidth and L1 bandwidth are matched for optimal scalability; if more towers are required, more boards can be inserted through the server.

“The trend toward network virtualization and O-RAN has brought us the opportunity to further disaggregate standard networks with the Xilinx T1 Telecom Accelerator Card,” said Dan Mansur, vice president of marketing for the Wired and Wireless Group (WWG) at Xilinx. development opportunities to help us expand into every segment of the 5G market. Working closely with our ecosystem partners, Xilinx hardware, IP and software are leading the innovation and implementation of 5G O-RAN networks.”

Daryl Schoolar, Practice Director, Fixed and Mobile Infrastructure, OMDIA, said: “As 5G infrastructure investments continue to grow to support new services and those requiring greater bandwidth, providing a solution that can accelerate systems to meet growing demands for scale and bandwidth A solution to your needs is critical. As operators’ interest in O-RAN and virtualization grows, the Xilinx T1 Telecom Accelerator Card will be an attractive solution. Not only does it address this At the same time, important aspects such as software and services have also been implemented on the edge side.”

Industry support

“We are proud to be working closely with Xilinx on the development of its T1 telecom accelerator card,” said Saurav Gupta, vice president of sales, VVDN (North America). and the industry-leading 5G IP used by the L1 offload solution.”

Mikael Rylander, senior vice president and general manager of the Radio Access Business Unit at Mavenir, said: “The diversification of Open RAN’s participation in enterprises and solutions will enable true innovation and a new way for the telecommunications industry to continue to grow. This Xilinx launch The Telecom Accelerator Card family is a powerful addition to 5G Open RAN, which will give the hardware flexibility to enable interoperability with a wide range of O-RAN equipment.”

Pasi Toivonen, Head of Edge Computing Platforms at Nokia, said: “We are delighted that Xilinx has successfully expanded into 5G telecom accelerator cards based on its extensive experience in the data accelerator market. Our Airframe design team at Nokia looks forward to continuing to work with Xilinx We want to work together to bring these exciting new options and capabilities to the growing 5G market.”


The T1 card is now available and sampling to customers worldwide. Mass production is expected to begin in early 2021.
