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.

    SLAU547A – January 2014 – Revised November 2014 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.

  • Page 2: Functional Description

    LMK04828, but the clocks are generated on board using the LMK04828 PLL and onboard 122.88 MHz VCXO. Figure 1 shows a simplified block diagram of the DAC3XJ8XEVM. See the schematics and bill of materials (BOM) located in the DAC3XJ8X Design Package (SLAC646) for detailed information. Table 1 contains descriptions of many of the connectors and jumpers available on the DAC3XJ8XEVM.

    NOTE: DAC3XJ8X GUI v1.1 or newer is required for DAC39J82 and DAC39J84 evaluation. 4. Start the GUI by going to Start Menu → All Programs → Texas Instruments DACs → DAC3XJ8X GUI. 5. Connect the EVM board to the computer with the supplied USB cable. A prompt to install the USB drivers is shown after the initial connection.

  • Page 4: Software Operation

    3.2.1 Quick Start Page The Quick Start page should be the starting point for all DAC3XJ8XEVM evaluation. Simply follow the steps to set the clocking mode, data rate, number of SerDes lanes, and interpolation. Before moving forward, the FPGA (TSW14J56 or FPGA development kit) should be programmed and waiting to establish the JESD204B link.
