Interfacing between TMS320C6678 and Spartan 6 via SerDes

Hi

I am going to connect the SerDes of TMS320C6678 to Spartan 6 GTP Transceivers.

Please Let me know is it enough to put 0.1uF capacitor per each line between devices for AC coupling?

Best Regards.

    The recommendation is to use an 0402 or smaller 0.1-μF ceramic capacitor for the C6678.  You can find this in section 11 of the SerDes Implementation Guidelines for Keystone I devices. You will have to check the documentation for the Spartan 6 to ensure that is compatible.
