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,
and ispMACH 5000VG
