Hi,

can i use the internal PLL of Cyclone 10 GX instead of using dedicated Clock input for DDR3 memory Clock?

All Development boards are using a dedicated clock, so is this mandatory?

Thanks!

Hi ,

Kidnly follow the recommendation from the ug to connect to the clock to the emif Ip,

 

The PLL reference clock pin may be placed in the address and command I/O bank or in a data I/O bank, there is no implication on timing.
