Recovered clock of aurora 8b10b

Hi,

 

Is it possible to receive data with the recovered clock in Aurora 8b10b design ? And if yes, how to provide the USER_CLK & SYNC_CLK of Aurora core?

 

Thanks

by default aurora takes RXREC clk. You can check in the gtp tile vhdl file

Have a look at the Aurora example design. It provides the way to provide different inputs to the Aurora core.

Correction ! The GTP can be generated 2 ways. One the aurora core generated GTP (ignore this), this is preferred to have the updated VHDL files for aurora core and for GTPs I'm using a GTP wizard with aurora protocol where I can choose the RXRECCLK for Rx side. The later gives me updates attributes for GTPs.
