Two 16-bit RF DACs Up to 12 GSPS and UltraScale FPGA

Need a Price Quote?

Overview

The XU-AWG is an XMC card with two 8-lane high speed serial links: one on XMC connector P15 and one on P16. These links can support several protocols (up to 8-lane PCIe, Aurora or user defined).

The XU-AWG XMC card features two AC-coupled single-ended DAC outputs with programmable DC bias. The Analog Devices AD9162 high-speed/high performance DACs employ synchronization support, interpolation, fixed latency and unique output circuits providing improved frequency synthesis in the 2nd and 3rd Nyquist zones.

  • Instrumentation and Automated Test Equipment

Software

  • VHDL FrameWork Logic
  • Windows/Linux Drivers
  • C++ DevKit

A Xilinx Kintex Ultrascale XCKU060 FPGA with 4GB DDR4 RAM memory provides a high-performance DSP core for demanding applications such as RADAR and wireless IF generation. The close integration of the analog front end, memory, and host interface with the FPGA enables real-time signal processing.

The XU-AWG XMC module couples a powerful multi-channel PCIe DMA architecture with a high performance 8 lane PCI Express link connected to the carrier. PCIe link speeds up to Gen3 are supported; however, the actual PCIe link performance depends on the XMC carrier and the host system.

The XU-AWG FPGA design can be fully customized using VHDL and the FrameWork Logic Devkit. Xilinx JESD204B IP license, purchased separately from Xilinx, is required for logic development.

A software development kit for host development includes C++ libraries and 64-bit drivers for Windows and Linux. An application demonstrating the module’s features, including streaming DAC samples from disk, is provided.
