Quartus II Design Example: Examples for altpll Megafunction User Guide

The altpll Megafunction User Guide offers two design examples that use the altpll megafunction to:

  • Generate an external differential clock from an enhanced PLL (as shown in Figure 1)
  • Generate and modify internal clock signals (as shown in Figure 2)

The following downloadable projects and files are used in this example:
