This configuration is very similar to Section 2.1.1 except that the feedback to the first PLL is driven by a clock output. This causes the clock outputs to have deterministic phase with the clock input. Since all the clock outputs can be synchronized together, all the clock outputs can be in phase with the clock input signal. The feedback to PLL1 can be connected internally as shown, or externally using FBCLKin (CLKin1) as an input port. It is also possible to use an external VCO in place of PLL2's internal VCO. Figure 2-2. Simplified Functional Block Diagram for 0-delay Dual Loop Mode 2.1.3 Single PLL Figure 2-3 illustrates the use case of single PLL mode. In single PLL mode only PLL2 is used and PLL1 is powered down. OSCin is used as the reference input. The internal VCO drives up to 6 divide/delay blocks which drive 12 clock outputs. The reference at OSCin can be used to drive up the OSCout0 port. OSCin can also optionally drive up to 4 of the clock outputs. It is also possible to use an external VCO in place of PLL2's internal VCO. Figure 2-3.
