Zynq UltraScale+ RFSoCs

Integrating a Comprehensive RF Analog-to-Digital Signal Chain

Zynq® UltraScale+™ RFSoCs integrate multi-giga-sample RF data converters and soft-decision forward error correction (SD-FEC) into a SoC architecture. Complete with an ARM® Cortex™-A53 processing subsystem, UltraScale+ programmable logic, and the highest signal processing bandwidth in a Zynq UltraScale+ device, the new family provides a comprehensive RF signal chain for wireless, cable access, test & measurement, early warning / radar, and other high performance RF applications.

Tools & Example Designs

A variety of solutions are available for developers to easily evaluate and debug designs on Zynq® UltraScale+™ RFSoCs devices. These solutions consist of tools, IP, and reference designs that enable a wide range of capabilities from performance evaluation to system level debug while the user design is running in hardware.

These tools serve as a platform to effectively configure and monitor Zynq UltraScale+ RFSoC features and accelerate product design cycles.

Name Description
RF Data Converter Evaluation Tool (ZCU111)

The evaluation tool consists of a reference design for the ZCU111 evaluation board and a custom GUI to configure the operation of the RF Data Converters and evaluate the performance of the RF-ADCs and RF-DACs.

RF Analyzer The RF Analyzer tool provides an easy way to configure and debug RF Data Converters in RFSoC devices on any user board. This tool enables debug capabilities using a simple GUI, interacting seamlessly with the RF Data Converter IP example design implemented on the user board.
RFSoC Frequency Planning Tool Interactive Excel spreadsheet that aids in frequency planning for Zynq UltraScale+ RFSoC devices.
