DAC3484EVM: Need help to choose DAC evaluation board?

Part Number: DAC3484EVM
Other Parts Discussed in Thread: DAC38J84EVM, DAC38RF82EVM,

Dear TI community

                                  I need a DAC evaluation boards that should be compatible with Xilinx ZYNQ ZC702 development board and it should be easily connected to LPC pin count of Zynq ZC702 Development boards.

                                  Is there any DAC evaluation board that fulfill my requirement?

    Imran,

    I am not sure what a ZC702 board is but we have tested both our DAC38J84EVM and DAC38RF82EVM with a ZC706. We use a TSW14J10EVM, also from TI, to allow us to run our HSDC Pro GUI on the Xilinx platform. See the attached document for more information regarding this setup.

    Regards,

    Jim

    Thanks Jim Seton

                                  We are only having ZC702 board. This board comes with TWO LPC (LOW PIN COUNT) and no HPC(High Pin Count). The board ZC706 that you suggest is having ONE HPC(High Pin Count) and ONE LPC (Low Pin Count). I can't connect the TSW14J10 FMC-USB Interposer Card to LPC of ZC 702. As it having HPC connector. Can i connect  DAC38J84EVM directly to the ZC702 board through external SPI connection available on DAC38J84EVM (DAC SPI or LMK SPI shown in figure below)?

    Thanks and Regards

    Imran,

    I do not know much about this board. Did Xilinx route all of the required signals on this LPC connector? In the past, on one of their boards, they only routed 4 serdes lanes. Did you verify that SYSREF, 8 data lanes, device clock and SYNC are all routed between these two boards? The schematic for the DAC EVM is attached to allow you to verify this. 

    Regards,

    Jim

    Hi Jim Seton

                         I went through schematics you gave me. I seems that this board having A,B,C,D,E,F,G,H,J,K pins (400 pins) of High Pin Connector. but the FPGA board I am having right now is having Low Pin Count Connector of Pins C,D,G,H (120 pins). The DAC3484EVM don't have all pins on C,D,G,H connectors of LPC, some of pins are of J,K which is part of HPC connector. It means I can't use this DAC board for my application. Is there any DAC evaluation board with SPI interface connection outside the FMC connector (External SPI pins to control DAC from FPGA GPIO pins not FMC connectors)?.

    Imran,

    On this EVM, you can reprogram U1 to use headers J24 to control the DAC SPI and J25 to control the LMK SPI. The source code is attached in case you want to attempt this.

    Regards,

    Jim
