Figure 2-5. Primary Clock Sources
Secondary Clock Sources
LatticeXP 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 2-6.
