5.6.6.2.1. Guideline: Clocking DPA Interfaces Spanning Multiple I/O Banks

DPA interfaces that use more than 24 channels span multiple I/O banks. Intel recommends that you feed the I/O PLL in each I/O bank of the DPA interface with its own dedicated refclk pin. Follow this recommendation to achieve the maximum DPA LVDS specifications listed in the device datasheet.
