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