The XU-TX is an XMC module which features two AC-coupled single-ended 16-bit DAC outputs with programmable DC bias. The DAC devices employed support synchronization, interpolation, and their unique output circuits allow improved frequency synthesis in the 2nd and 3rd Nyquist zones. This can shift the Nyquist null frequency in the output spectrum to two times the typical Nyquist null frequency. The maximum sample rate of the DAC IC is 10.2 GSPS, the maximum external direct clocking rate is 5.1 GSPS and the on board PLL can generate clocks up to 4.8 GHz. The DACs' JESD 204B interfaces can stream data with transfer rates up to 5.1 Gsps.A Xilinx Kintex Ultrascale XCVU060/085 FPGA with 4GB DDR4 RAM memory provides a very high performance DSP core for demanding applications such RADAR and wireless IF generation. The close integration of the analog I/O, memory and host interface with the FPGA enables real-time signal processing at rates exceeding 7000 GMAC/s.The module supports tw
