Edge Clock Sources
Edge clock resources can be driven from a variety of sources at the same edge. Edge clock resources can be
driven from adjacent edge clock PIOs, primary clock PIOs, PLLs and clock dividers as shown in Figure 2-8.
Figure 2-8. Edge Clock Sources
Note: This diagram shows sources for the XP2-17 device. Smaller LatticeXP2 devices have two GPLLs.
