11 / 237 page  2-7 Architecture Lattice Semiconductor LatticeSC/M Family Data Sheet • Two outputs per PLL • Clock divider outputs • Digital Clock Select (DCS) block outputs • Three outputs per SERDES quad Figure 2-5 shows the arrangement of the primary clock sources. Figure 2-5. Clock Sources Primary Clock Routing The clock routing structure in LatticeSC devices consists of 12 Primary Clock lines per quadrant. The primary clocks are generated from 64:1 MUXs located in each quadrant. Three of the inputs to each 64:1 MUX comes from local routing, one is connected to GND and rest of the 60 inputs are from the primary clock sources. Figure 2-6 shows this clock routing.
