Honored ContributorALT2GXB clock handling
Hi, I want to use one ALT2GXB (8.0 Build 231 SP 1 SJ Web Edition) in PIPE mode for a single lane PCIe configuration (generated through MegaWizard Plugin Manager, of course) on a StratixII GX. ...

Honored ContributorI ran into a similar problem. My thought was to input the PCIe refclk to an enhanced PLL. Output a 125MHz clock to the dedicated refclk input of the GXB. Generate an internal 125MHz clock and other needed frequencies. This way, you get 0PPM difference between your internal 125MHz and the 125MHz going to the dedicated refclk inputof the GXB. Not sure if this will meet your requirements but it should work.
