For Mass 5G Radio Deployments

Xilinx is a rather big player in 5G infrastructure with its very attractive Zynq RFSoC, and today the company announced a new Zynq RFSoC DFE to help accomplish the evolving standard of 5G NR.

The new class of adaptive radio platforms combines flexibility for evolving 5G standards and a hardened radio digital front-end for performance, power, and cost-effectiveness. 5G, as many are aware, is at the beginning of its regulatory journey. Current Release 15 5G was locked down in 2018will evolve to a new Release 16 specification (finished in mid-2020) and later to Release 17 (expected in 2022). Adaptability and programmability play a significant role in the 5G infrastructure. The carrier can add new release support and feature just by updating hardware without expensive on-location replacement of the infrastructure hardware.

 Adapt to new radio and standards

The new Zynq RFSoC DFE is a breakthrough class of adaptive radio platforms designed to meet the evolving standards of 5G NR wireless applications. Zynq RFSoC DFE combines hardened digital front-end (DFE) blocks and adaptable logic to build high performance, low power, and cost-effective 5G NR radio solutions for a broad array of use cases ranging across 5G low-, mid-, and high- band spectrum.

Zynq RFSoC DFE offers the best balance of technologies between the cost economies of an ASIC using hardened blocks and the flexibility, scalability, and time-to-market benefits of a programmable and adaptive SoC.

5G radio requires solutions that not only meet bandwidth, power, and cost challenges for widespread deployment but must also adapt to the three key 5G use cases: enhanced Mobile Broadband, Massive Machine Type Communication, and Ultra-Reliable Low-Latency Communication.

In addition, solutions must scale for evolving 5G standards such as OpenRAN (O-RAN) as well as new and disruptive 5G business models. Zynq RFSoC DFE integrates hardened DFE application-specific blocks for 5G NR performance and power savings while also offering the flexibility to integrate programmable adaptive logic to enable a futureproof solution for evolving 5G 3GPP and O-RAN radio architectures.

"For the first time, Xilinx is providing a wireless radio platform with more hardened application-specific IP than adaptive logic to address low power and low cost 5G requirements", said Liam Madden, executive vice president and general manager, Wired and Wireless Group at Xilinx. "With the market needs around 5G evolving, integrated RF solutions need to be adaptable to address future standards. Zynq RFSoC DFE provides the optimal balance between that adaptability and fixed function IP."

2X performance per watt

Zynq RFSoC DFE offers 2X performance-per-watt compared to its prior generation and scales from a small cell to massive MIMO macrocells. The solution is the industry's only direct RF platform that enables carrier aggregation/sharing, multi-mode, multi-band 400MHz instantaneous bandwidth in all FR1 bands, and emerging bands up to 7.125GHz.

A 7.125GHz of Analog Bandwidth with Hardened DFE Subsystem can deliver more processing per channel, greater instantaneous bandwidth, more integration, half the DC power for a given use case still be a cost-effective solution for the high volume.

When used as a millimeter-wave intermediate frequency transceiver, it provides up to 1,600MHz of instantaneous bandwidth. Zynq RFSoC DFE is built so that customers can bypass or customize the hard IP blocks. For example, customers can leverage Xilinx's field-proven DPD that supports existing and emerging GaN power amplifiers or insert their unique DPD IP.

"As 5G continues to evolve in both commercial deployments and new use cases, it is critical for the supply chain to provide flexible components for vendors to create cost effective, adaptive and futureproof equipment. Open RAN takes this requirement to a much higher level, where flexible designs are paramount to its success," said Dimitris Mavrakis, senior research director of 5G at ABI Research. "With its balance of hardening and adaptable logic, Zynq RFSoC DFE is a unique offering which combines the cost characteristics typically found in ASICs while providing the design flexibility and customization available in an FPGA."

Availability

Zynq RFSoC DFE design documentation and support is available to early access customers, with shipments expected during the first half of 2021. More data on the entire family of Zynq UltraScale+ RFSoCs, including the newest Zynq RFSoC DFE are here
