Xilinx ships 5G O-RAN card for virtual baseband units

Wednesday 16 September 2020 | 10:46 CET | News

Xilinx announced the T1 Telco Accelerator Card for O-RAN distributed units (O-DUs) and virtual baseband units (vBBUs) in 5G networks. Built using the same field-proven Xilinx silicon and IP already being deployed in 5G networks, the T1 card is the only multi-function PCIe form factor card which performs both O-RAN fronthaul protocols and layer 1 offload, the company said. 

With its advanced offload functionalities, the T1 card is designed to provide a reduction in the number of CPU cores required in a system. The T1 card also enables the O-DU to deliver greater 5G performance and services while reducing overall system power consumption and cost compared to competitive offerings. 

The demand for O-DU and vBBU products is rapidly increasing because they provide an open and standard platform for a wide range of 5G virtualised services. The T1 card is a small form factor, single-slot card that can be plugged into standard x86 or non-x86 servers to achieve the real-time protocol processing performance required for 5G virtualised O-DU platforms. In addition, it offloads line-rate and compute-intensive functions including: channel encoding/decoding using hardened LDPC and Turbo codecs, rate matching/de-matching, HARQ buffer management, and more, freeing the processor cores for running other services - the true promise of virtualisation. The T1 card simplifies 5G deployments by offering a platform through ecosystem partners that includes both O-RAN fronthaul and 5G NR layer 1 reference designs, as well as pre-validated software to enable operators, system integrators, and OEMs to get to market quickly. 

The offloading of critical channel coding functions from the CPU to the T1 card delivers up to 45x encoding and 23x decoding throughput improvement relative to the same server without acceleration. The T1 card enables the use of fewer CPU cores, driving down system cost and overall power consumption. In addition, for O-RAN fronthaul termination, it can process multiple sectors of 5G NR 4TRX at 100 MHz OBW with its 50 Gbps of optical ports. The Fronthaul and L1 bandwidths are matched for optimal scalability.
