Figure 15. PLL Block Diagram
Figure 16. Connection of Optional PLL Inputs and Outputs
In order to facilitate the multiply and divide capabilities of the PLL, each PLL has dividers associated with it: M, N
and K. The M divider is used to divide the clock signal, while the N divider is used to multiply the clock signal. The
K divider is only used when a secondary clock output is needed. This divider divides the primary clock output and
feeds to a separate global clock net. The V divider is used to provide lower frequency output clocks, while maintain-
ing a stable, high frequency output from the PLL’s VCO circuit. The PLL also has a delay feature that allows the out-
put clock to be advanced or delayed to improve set-up and clock-to-out times for better performance. For more
information on the PLL, please refer to TN1003, sysCLOCK PLL Usage Guide for ispXPGA, ispGDX2, ispXPLD
