35 / 334 page Fusion Family of Mixed Signal FPGAs Revision 4 2-19 Clocking Resources The Fusion family has a robust collection of clocking peripherals, as shown in the block diagram in Figure 2-16. These on-chip resources enable the creation, manipulation, and distribution of many clock signals. The Fusion integrated RC oscillator produces a 100 MHz clock source with no external components. For systems requiring more precise clock signals, the Fusion family supports an on-chip crystal oscillator circuit. The integrated PLLs in each Fusion device can use the RC oscillator, crystal oscillator, or another on-chip clock signal as a source. These PLLs offer a variety of capabilities to modify the clock source (multiply, divide, synchronize, advance, or delay). Utilizing the CCC found in the popular ProASIC3 family, Fusion incorporates six CCC blocks. The CCCs allow access to Fusion global and local clock distribution nets, as described in the "Global Resources (VersaNets)" section on page 2-12.
