XU-TX xmc Two 5.1 GSPS 16-bit DACs Xilinx UltraScale

Innovative Integration

Flag/report this product
The XU-TX - an XMC module featuring two, AC-coupled, single-ended 16-bit DAC outputs with programmable DC bias. The DAC devices employed support synchronization and interpolation and their unique output circuits allow improved frequency synthesis in the 2nd and 3rd Nyquist zones, to shift of the Nyquist null frequency in the output spectrum by a factory of two. The DAC ICs may be clocked at up to 5.1 GHz via an onboard, ultra-low-jitter PLL. A unique feature of th PLL guarantees multi-board synchronization when supplied a 1/16th -rate external reference and trigger. Sixteen high-speed serial links connect to the host (eight via XMC connector J15, and eight via J16). 8000 MB/s PCIe gen3 and Aurora protocols, respectively are supported. A Xilinx Kintex UltraScale XCVU060/085 FPGA lies at the heart of the product, supported by with 8 GB DDR4 and 4 MB of QDRAM memory, providing a very high performance DSP core for demanding applications such RADAR and wireless IF generation. The close integration of the analog IO, memory and host interface with the FPGA enables real-time signal processing at rates exceeding 7000 GMAC/s. Applications include: High Speed Arbitrary Wave Generation, Wireless MIMO transmitter, RADAR Waveforms, and Electronic Warfare.
