Honored ContributorPCIe Gen-1 Application clock
Hi, We are planning to use PCIe Gen-1 core on Stratix IV GX device. As per datasheet, minimum Application/core clock is 62.5 MHz. Is it possible, to reduce Application clock less than 62.5 MHz?...

Honored ContributorI agree. There is probably a good reason why there is a minimum clock frequency for the core. You could use a 62.5MHz clock for the core and keep using 40MHz for your design if you absolutely need to, you will just have to be careful with any signal crossing the clock domains, for example by using double clock fifos.
