FMC DAC Adapter Rev D - compatibility with Xilinx ML 605?
I am trying to interface Xilinx ML 605 to DAC34H84 using the FMC DAC adapter Rev D. the FMC adapter can't be connected to the HPC connector in the Xilinx board . This is because the power connector on the DAC board prevents the HPC connector on the adapter from fitting in to that in ML 605. (The power connector on the DAC board hits a switch and a PCIe connector on ML605). What is a solution to this?
I have connected the DAC34H84 EVM to the ML605, and I do see the issue that you are describing.
One quick solution is to remove the J18 connector if you have access to solder rework station. You can then apply the 6V through Test Point TP12 and TP13 via external power supplies.
Another solution is to use extension cables such as the Vita57 Flex Datalinks cable.
We have used the SCF-154426-02-MA and the SCF-155383-01-MA cables (both are 10inches) before and they worked pretty well. They have 5inches options available.
We will look into this more to see if there are other options for this.
Thanks Kang! I shall try this out and let you know.
We did not find other easy methods to connect to the ML605 board besides the two methods that I have described above. We are planning to extend the length of adapter board to prevent future space constraints when interfacing with other EVMs. We don't have a timeline yet but I will keep you posted.
