Critical Issue
Description
The Quartus II Fitter reports an error when you use PLL-generated clock inputs of 67.5 MHz frequency in SDI-SD MegaCore targeting Stratix GX devices.
This issue affects all Stratix GX SDI-SD MegaCore functions with PLL-generated clock inputs of 67.5 MHz frequency.
The design cannot be fitted in the device.
Resolution
Set the input clock to 29.7 MHz frequency so that the PLL generates the frequency of the output clock to 74.25 MHz.
This issue will be fixed in a future version of the SDI MegaCore function.
