DAC3XJ8XEVM
The DAC3XJ8XEVM is an evaluation module (EVM) designed to evaluate the DAC3XJ8X family of high-
speed, JESD204B interface DACs (DAC37J82, DAC37J84, DAC38J82, DAC38J84, DAC39J82,
DAC39J84). The EVM includes an onboard clocking solution (LMK04828), transformer coupled outputs,
full power solution, and easy-to-use software GUI and USB interface.
The DAC3XJ8XEVM is designed to work seamlessly with the TSW14J56EVM, Texas Instruments’
JESD204B pattern generator card, through the High Speed Data Converter Pro (HSDCPro) software tool
for high-speed data converter evaluation. The DAC3XJ8XEVM was also designed to work with many of
the development kits from leading FPGA vendors that contain an FMC connector.
