We will also delve into the partner overan front hall reference design, which utilizes the RFSoC DFE (Digital Front End). This reference design provides cost-effective solutions for massive MIMO and O-RAN radios, making it a valuable asset in the telecommunications industry. Let's dive in and explore how this groundbreaking technology works and its potential benefits.
AMD Xeilings Zinc Ultrascale Plus RFSoC Products
AMD's Xeilings Zinc Ultrascale Plus RFSoC products are revolutionizing the telecommunications industry. These products integrate key radio IP in a hardened format, including Crest Factory reduction, digital pre-distortion, and Lo-Fi functions. With an AT88R configuration, they offer cost-effective solutions for massive MIMO and O-RAN radios.
Partner Overan Front Hall Reference Design
The partner overan front hall reference design is built upon the RFSoC DFE, AMD's latest product. This reference design combines the partner's own IP with AMD Xilinx IP, providing an efficient and seamless integration of features. The design is implemented on the ZCU 670 evaluation kit, specifically created for the RFSoC DFE. This reference design showcases the capabilities and performance of the RFSoC DFE, making it an invaluable tool for system development and testing.
RFSoC DFE (Digital Front End)
The RFSoC DFE is a cutting-edge product by AMD that offers a range of features aimed at optimizing radio performance. It seamlessly integrates key radio IP, such as Crest Factory reduction, digital pre-distortion, and Lo-Fi functions. With its AT88R configuration, it ensures cost-effective solutions for massive MIMO and O-RAN radios. The RFSoC DFE is available on the ZCU 670 evaluation kit, creating a powerful platform for developing and testing radio systems.
ZCU 670 Evaluation Kit
The ZCU 670 evaluation kit is a specialized platform designed specifically for the RFSoC DFE. This evaluation kit incorporates the ZCU 670 RF evaluation platform, equipped with the RFSoC DFE device (ZU67DR). The ZU67DR device boasts an 8x8 configuration, integrating not only the hard DFE IP but also the RF DSP O-RAN reference design. This evaluation kit provides a comprehensive and versatile environment for testing and evaluating the capabilities of the RFSoC DFE.
RF Evaluation Platform Setup
In the center of the demonstration setup, we have the ZCU 670 RF evaluation platform. This platform houses the RFSoC DFE device (ZU67DR), which is an 8x8 configuration with integrated hard DFE IP and RF DSP O-RAN reference design. To test the system, an XM 655 board is connected to the ZCU 670, allowing for low, mid, and high output frequencies. The setup enables maximum signal dynamic range without post amplification, ensuring accurate and reliable results.
Viv tm500 ODU Emulator
The Viv tm500 ODU emulator plays a pivotal role in the demonstration setup. Connected to the ZCU 670 via a 25 Gig Ethernet cable, the tm500 is responsible for sending pre-configured 3GPP compliant download data, user data, and control plane information. It captures uplink data from the ZCU 670, which is then passed onto the BSA software for analysis. The Viv tm500 ODU emulator streamlines the testing and analysis process, providing valuable insights into system performance.
Rhodium Schwartz Test Equipment
To analyze the downlink data generated by the Viv tm500 ODU emulator, Rhodium Schwartz test equipment is employed. The downlink data is fed from the tm500 to the ZCU 670 and then passed into the Rhodium Schwartz Spectrum analyzer. This analysis allows for the characterization of signal quality based on 3GPP metrics. The Rhodium Schwartz test equipment provides accurate and precise measurements, ensuring a thorough evaluation of system performance.
RFDSP Oru Reference Design
The RFDSP Oru reference design is a vital component of the overall system setup. It operates on an AT88R 7.2x split, incorporating the front hall Lo-Fi and DFE reference design. Supporting C, U, and S traffic, it provides an API for implant traffic and has been optimized for the hard IP in the RFSoC DFE. The RFDSP Oru reference design includes its own software development environment (SDE), assisting customers in product development and testing. Its efficiency and compatibility make it an essential part of the system.
Downlink Data Analysis
The demonstration showcases the effectiveness of the entire system working together. The downlink data, generated by the Viv tm500 ODU emulator and transmitted to the RFSoC via the 25 Gig Ethernet cable, is analyzed. The reference design by RFDSP is configured for a 4t4r 100-megahertz radio, transmitting at 1.9 gigahertz. The Rhodium Schwartz signal analyzer demonstrates excellent signal fidelity with an EVM (Error Vector Magnitude) of 0.77 percent, surpassing the requirement of 4.5 percent. This analysis highlights the impressive performance of the RFSoC DFE and validates the efficiency of the entire reference design.
Uplink Data Analysis
The uplink data analysis is equally important in assessing system performance. The uplink data is generated by the SMM 100a Radiance Short Signal Generator, fed into the RFSoC at 1.9 gigahertz, and processed using the RFDC IP. The RFDSP reference design captures the uplink data along with control plane information and passes it back to the Viv tm500. The data is then analyzed using the Rhodium Schwartz VSA software, providing insights into RF performance and EVM. The analysis reveals similar performance characteristics to the downlink Channel, affirming the effectiveness of the RFSoC DFE and the reference design.
Conclusion
In this demonstration, the partner RFDSP's 7.2x full O-RAN solution showcased the immense capabilities of the RFSoC DFE. The integration of partner IP and AMD Xilinx IP culminated in a robust reference design that offers exceptional performance in cost-effective solutions for massive MIMO and O-RAN radios. The ZCU 670 evaluation kit, along with the Viv tm500 ODU emulator and Rhodium Schwartz test equipment, formed a powerful setup that accurately analyzed both downlink and uplink data. The demonstration reiterated the reliability and efficiency of the RFSoC DFE and its potential in transforming radio systems.
