SPEEDLOCKING FOR GUARANTEED FIXED TIMING  
The unique MACH 1 & 2 architecture is designed for high performance—a metric that is met in  
both raw speed, and even more importantly, guaranteed fixed speed. The design of the switch  
matrix and PAL blocks guarantee a fixed pin-to-pin delay that is independent of the logic required  
by the design. Other non-Lattice/Vantis CPLDs incur serious timing delays as product terms expand  
beyond their typical 4 or 5 product term limits (Figure 8). Speed and SpeedLocking combine to  
give designers easy access to the performance required in todays designs.
