FMC-DAC Adapter == BEWARE of old revisions!

Nevada Sanchez

Other Parts Discussed in Thread: DAC34H84

I've spend an unfortunate amount of time trying to debug a design with my DAC3484EVM only to realize that the FMC-DAC adapter I (quite recently) ordered is a Rev. B. The pinout on this board is quite a bit different than what is shown in the Rev. D schematics (the only ones I can find). The pinout I found with my multi-meter is:

D0 -> H28, H29

D1 -> D20, D21

D2 -> H25, H26

D3 -> H22, H23

D4 -> H19, H20

D5 -> H16, H17

D6 -> H13, H14

D7 -> H10, H11

D8 -> G36, G37

D9 -> G33, G34

D10 -> G30, G31

D11 -> G27, G28

D12 -> G24, G25

D13 -> G21, G22

D14 -> G18, G19

D15 -> G15, G16

DCLK -> C22, C23

CLKOUT -> H4, H5

The 8 MSB's and the clock signals are the same as Rev. D, but the most frustrating difference is that the FRAME, SYNC, and PARITY signals have NO connection whatsoever to the FMC connector!

I'm posting this for a few reasons:

1) TI, please stop sending Rev. B boards out!,

2) If you have a Rev. B board, I hope this helps.

3) Tech support is taking a while to get back to me about sending a replacement. Is there anyone within TI that can help me get a Rev. D board more quickly?

Nevada,

A few weeks ago we recalled all of the previous revs of the adapter board and have the rev D at the estore.

I can get a revD send to you asap. I will message you privately for contact info.

Regards,

Ken.

Hi Ken,

Do you guys still have Rev D for the FMC-DAC-Adatper Card? We need Rev D, but the one we received is Rev B. Can you help in this?

Thank you very much for your help.

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 to fit 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?

thanks!
