Multiple SRIO rates on same device



Our group is working with the Kintex 410 and we have 16 avaliable GTX ports, which we are using for SRIO. Is it possible to have different rates between the 16 GTX ports?


That is, can we run a bank of width 4 at 1.25Gb and another bank of width 4 at 3.125Gb on the same device? If so, is there any documentation which will be useful for how to set up reference clocks etc.? Or, does one device only support one rate?

Re: Multiple SRIO rates on same device



You can run different GTX ports in different banks at different rates using multiple IPs. 

As the instantoation of the IP is difefrent I do not thing you should have any issue. Please go through "shared logic" and "resources sharing" sections fof PG007 for more details on clock sharing.


Hope this helps
