It is also possible to use the DCM to drive a PLL. This setup reduces the overall jitter of
both the source clock and the DCM clock output. In this case, only up to two of the DCM
output clocks can drive the PLL. Therefore, only up to two DCM clocks can access the PLL
and benefit from the reduced jitter.
Figure 2-15
illustrates the direct connection between DCM and PLL within a CMT. Only one DCM
output can drive PLL using the direct connection within a CMT without routing through a
global buffer (BUFG). The DCM and PLL can be within the same or different CMTs.
