Hi all,

I want to connect two Freeware ML605 boards and was thinking to use SERDES.

The intended data speed is 800Mbps.  My data bus is 8 bits wide and my system clock is 100MHz.

So, I have to connect my system clock to CLKDIV (slower clock).

How about the high speed clock to drive serial link? Where should I connect to?

Hi,

Take a look at this file:

http://www.xilinx.com/support/documentation/user_guides/ug361.pdf

ISERDES - page 125. Table 3-1.

OSERDES - page 147. Table 3-6. 

I hope it will be helpful ;]

Hello,

I also think these two application notes are excellent at descibing how to use multi-bit SERDES channels betweeen devices with automatic alignment for maximum speed.

Start with this:

But also look at this:
