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/DLLs and clock dividers as shown in Figure 2-10.
Figure 2-10. Edge Clock Sources
Primary Clock Routing
The clock routing structure in LatticeECP2 devices consists of a network of eight primary clock lines (CLK0 through
CLK7) per quadrant. The primary clocks of each quadrant are generated from muxes located in the center of the
device. All the clock sources are connected to these muxes. Figure 2-11 shows the clock routing for one quadrant.
Each quadrant mux is identical. If desired, any clock can be routed globally
