sysCLOCK Phase Locked Loops (PLLs)
The PLL clock input, from pin or routing, feeds into an input clock divider. There are three sources of feedback sig-
nal to the feedback divider: from CLKOP (PLL Internal), from clock net (CLKOP) or from a user clock (PIN or logic).
There is a PLL_LOCK signal to indicate that VCO has locked on to the input clock signal. Figure 2-11 shows the
sysCLOCK PLL diagram.
The setup and hold times of the device can be improved by programming a delay in the feedback or input path of
the PLL which will advance or delay the output clock with reference to the input clock. This delay can be either pro-
