Clock Distribution Network
LatticeECP3 devices have eight quadrant-based primary clocks and eight secondary clock/control sources. Two
high performance edge clocks are available on the top, left, and right edges of the device to support high speed
interfaces. These clock sources are selected from external I/Os, the sysCLOCK PLLs, DLLs or routing. These clock
sources are fed throughout the chip via a clock distribution system.
Primary Clock Sources
LatticeECP3 devices derive clocks from six primary source types: PLL outputs, DLL outputs, CLKDIV outputs, ded-
icated clock inputs, routing and SERDES Quads. LatticeECP3 devices have two to ten sysCLOCK PLLs and two
DLLs, located on the left and right sides of the device. There are six dedicated clock inputs: two on the top side, two
on the left side and two on the right side of the device. Figures 2-9, 2-10 and 2-11 show the primary clock sources
for LatticeECP3 devices.
