Description
Yes. Cyclone® IV GX devices support 133 MHz DCLK fMAX in Fast Passive Parallel (FPP) configuration.
Table 1-28 in the Cyclone® IV Device Handbook volume 3 says DCLK fMAX is 100 MHz for 1.2 V VCCINT in Fast Passive Parallel (FPP) configuration. But this is not correct. It should be 133 MHz.
Resolution
Ignore 100 MHz DCLK fMAX for 1.2 V VCCINT in Fast Passive Parallel (FPP) configuration in Table 1-28 of the Cyclone® IV Device Handbook volume 3.
Cyclone® IV GX devices support 133 MHz DCLK fMAX.
