Thanks bzyzny.
To use the 7.5ns symbol time, I think that they all use the 400MHz system clock. because 1/400MHz = 2.5ns , 2.5ns * 3 = 7.5ns . Link configuration registers 0x80..0x88 can be used to get 7.5ns symbol time.

Hi, bzyzny and henk, thank you for your reply.

I mean that if the xConnect link of XS1 and XCORE200 are all using 2 wires and 7.5ns symbol time,they should have the same link speed. Am I right?

Hi,all
According their datasheet, why the 2b link bandwidth(stieaming) of the xu208-128-64 is 100MBit/s and the XS1-U6A-64-FB96 is 125MBit/s , and they are all the same 7.5ns symbol time ? I think that they should have the same performance. I hope somebody can explain this.

Thanks.
