The DAC39RF20EVM is an evaluation board for evaluating the DAC39RF20 family of digital-to-analog converters (DAC) from Texas Instruments. The EVM can be used to evaluate the performance of the DAC up to 22-GSPS sampling rate. The EVM is designed to work with the FPGA-based pattern generator card TSW14J59EVM. The available FMC connector on the EVM also makes interfacing the DAC to FPGA development boards from third-party vendors possible. An easy-to-use software interface GUI to control the DAC and an onboard LMK04828 clock chip through SPI are also available.
<ul>
<li>Two balun-coupled output networks per DAC output allowing singled ended signal evaluation</li>
<li>A 5MHz to 10GHz low band balun for first Nyquist evaluation</li>
<li>A 2GHz to 18GHz high band balun for second and third Nyquist evaluation</li>
<li>A LMK04828 clock distribution chip for distributing FPGA reference clocks and SYSREF for subclass 1 operation</li>
<li>A balun-coupled clock input network to test the DAC performance with an external low-noise clock source</li>
<li>An FMC+ with high-speed serial data connections for full JESD204C testing of all 16 lanes</li>
