LatticeECP/EC Family Data Sheet
Secondary Clock Sources
LatticeECP/EC devices have four secondary clock resources per quadrant. The secondary clock branches are
tapped at every PFU. These secondary clock networks can also be used for controls and high fanout data. These
secondary clocks are derived from four clock input pads and 16 routing signals as shown in Figure 2-7.
Figure 2-7. Secondary Clock Sources
Clock Routing
The clock routing structure in LatticeECP/EC devices consists of four Primary Clock lines and a Secondary Clock
network per quadrant. The primary clocks are generated from MUXs located in each quadrant. Figure 2-8 shows
this clock routing. The four secondary clocks are generated from MUXs located in each quadrant as shown in
Figure 2-9. Each slice derives its clock from the primary clock lines, secondary clock lines and routing as shown in
