DLL Range Specifications
Table 51: DLL Frequency Range Specifications for Arria 10 Devices—Preliminary
Arria 10 devices support memory interface frequencies lower than 667 MHz, although the reference clock that feeds the DLL must be at least 667 MHz. To
support interfaces below 667 MHz, multiply the reference clock feeding the DLL to ensure the frequency is within the supported range.
