Genesys 2 FMC

Recommended Posts

Hi,

We'd like to buy a Genesys 2 board, but I have a few questions.

There are 80 differential pairs wired on FMC connector but  22 pairs can only be used if FMC provide power to the HB  bank. Do you think we could  provide this power signal by redirecting an fpga power signal back to HB bank on our FMC ?

Regards,

Cedric

Hi @cchamp,

You can use the VADJ power rail to redirect it back to the board like you describe as long as you do not exceed the 5A limit as shown in the reference manual here in section 2 power supplies in Table 2. Voltage rail power settings VADJ (1.2-3.3 V).

cheers,

Jon

Hi @cchamp,

Yes. Also just to re-iterate that you need to make sure that you are not exceeding the current limitations I mentioned in the above comment.

cheers,

Jon
