What is the frequency range for the DCLK configuration internal oscillator, in Cyclone® IV devices? - What is the frequency range for the DCLK configuration internal oscillator, in Cyclone® IV devices? Description The Cyclone® IV Device Handbook does not contain the frequency range for the internal oscillator that derives the DCLK output in Active Serial (AS) and Active Parallel (AP) configuration modes. The table below contains the range for the two frequency options: Oscillator Minimum Typical Maximum Unit 40 MHz 20 30 40 MHz 20 MHz 10 15 20 MHz Resolution This information has been included in the most recent version of the Cyclone® IV Device Handbook.
