4-channel, 1.25 GHz D/A XMC for waveform generation

By eeNews Europe

Model 71871 features two Texas Instruments DAC3484s for four independent analog outputs each with its own digital upconverter and 16-bit D/A with sampling rates to 1.25 GHz. A Xilinx Kintex Ultrascale FPGA provides factory-installed functions that include a sophisticated D/A waveform generation IP module. Users are easily able to deliver waveforms stored in either on-board memory or off-board host memory to the four D/As. Complex output waveforms, each with bandwidths up to 250 MHz, can be independently translated to programmable IF frequencies.

Model 71871 is available with a range of Kintex UltraScale FPGAs for applications depending on the processing task from the entry-level KU035 with 1,700 DSP slices to the high-performance KU115 with 5,520 DSP slices. For applications not requiring large DSP resources or logic, a lower-cost FPGA can be installed.

Two front-panel μSync connectors allow multiple modules to be synchronized. Model 71871 can be optionally configured with a P14 PMC connector with 24 pairs of LVDS connections to the FPGA for custom I/O to the carrier board. An optional P16 XMC connector adds an 8X gigabit link to the FPGA to support serial protocols.
