Xilinx and TI to develop DFEs for energy efficient 5G radios: Page 2 of 2

Xilinx and TI collaborate to develp energy efficient 5G radio using the Zynq UltraScale+ MPSoC family
The collaboration addresses the next generation of LTE and 5G small cells with scalable and adaptable digital front-ends to increase the energy efficiency of lower antenna count radios.

Xilinx's Adaptable Digital RF IP includes specialist functionality of Crest Factor Reduction (CFR) and Digital Pre-distortion (DPD. It claims to be the only product that can support a wide range of radio bandwidths and carrier configurations. Also, by being tightly integrated with the rest of the PHY processing implemented in the Zynq UltraScale+ MPSoC device, it can handle the increasingly complex signal dynamics of multi-RAT and 5G waveforms which are challenging for standalone DPD implementations. The PA technology is also evolving quickly to address these new radio requirements with broader adoption of GaN and new architectures. Adapting to these new technologies is key to maximizing the efficiency of the PA.

“PA linearity for spectral efficiency and RF power delivery is key to achieving the performance benefits of 5G New Radio systems. Wide-bandwidth transceivers like the AFE7769 help to address higher-order PA nonlinearities and enable more efficient power delivery,” said Karthik Vasanth, vice president and business unit manager, data converters, at TI. “With this implementation, designers can address the market needs for higher instantaneous bandwidth and antenna counts to support MIMO (multiple-input, multiple-output) applications while also offering scalability to meet system cost targets.”

To speed development and allow developers to evaluate these systems Xilinx provides a range of development platforms and tools. More information about the collaboration can be found in the blog here which also features a video demonstration.
