Primary Clocks
Each quadrant receives up to eight primary clocks. Two of these clocks provide the Dynamic Clock Selection (DCS)
feature. The six primary clocks without DCS can be specified in the Pre-map Preference Editor as ‘Primary Pure’
and the two DCS clocks as ‘Primary-DCS’.
The sources of primary clocks are:
• PLL outputs
• CLKDIV outputs
• Dedicated clock pins
• Internal nodes
Secondary Clocks
The LatticeXP2 secondary clocks are a flexible region-based clocking resource. Each region can have four inde-
pendent clock inputs. Since the secondary clock is a regional resource, it can cross the primary clock quadrant
boundaries.
There are eight secondary clock muxes per quadrant. Each mux has inputs from four different sources. Three of
these are from internal nodes. The fourth input comes from a primary clock pin. The input sources are not neces-
sarily located in the same quadrant as the mux. This structure enables global use of secondary clocks.
The sources of secondary clocks are:
• Dedicated clock pins
• Clock Divider (CLKDIV) outputs
• Internal nodes
Table 9-2 lists the number of secondary clock regions in LatticeXP2 devices.
Table 9-2. Number of Secondary Clock Regions
Edge Clocks
The LatticeXP2 device has two Edge Clocks (ECLK) per side. These clocks, which have low injection time and
skew, are used to clock I/O registers. Edge clock resources are designed for high speed I/O interfaces with high
fanout capability. Refer to Appendix B for detailed information on ECLK locations and connectivity.
The sources of edge clocks are:
• Left and Right Edge Clocks
• Top and Bottom Edge Clocks
Edge clocks can directly drive the secondary clock resources and general routing resources. Refer to Figure 9-21
for detailed information on edge clock routing.
