What is the typical value for the 40 MHz DCLK in Cyclone IV devices? - What is the typical value for the 40 MHz DCLK in Cyclone IV devices? Description For Cyclone® IV devices, the typical value for the 40 MHz DCLK will be 33MHz. This typical DCLK frequency will be the same for both Active Serial (AS) and Active Parallel (AP) modes. Resolution This will be added to Table 1-29 in a future version of the Cyclone IV Device Handbook.
