13.3.1. Example Programming
Type a value for the crystal resonator frequency in MHz in the reference crystal box. This frequency provides the basis for all of the PLL
calculations that follow.
Next, click on the PLL A box. A pop-up screen similar to Figure 15 should appear. Type in a desired output clock frequency in MHz, set
the operating voltage (3.3 V or 5 V), and the desired maximum output frequency error. Pressing calculate solutions generates several
possible divider and VCO-speed combinations.
Figure 15: PLL Screen
For a 100 MHz output, the VCO should ideally operate at a higher frequency, and the reference and feedback dividers should be as
small as possible. In this example, highlight solution #7. Notice the VCO operates at 200MHz with a post divider of 2 to obtain an
optimal 50 percent duty cycle.
Now choose which mux and post divider to use (that is, choose an output pin for the 100 MHz output). Selecting A places the PostDiv
value in solution #7 into post divider A and switches mux A to take the output of PLL A.
The PLL screen should disappear, and now the value in the PLL A box is the new VCO frequency chosen in solution #7. Note that mux
A has been switched to PLL A and the post divider A has the chosen 100MHz output displayed.
Repeat the steps for PLL B.
PLL C supports two different output frequencies depending on the setting of the SEL_CD pin. Both mux C and mux D are also affected
by the logic level on the SEL_CD pin, as are the post dividers C and D (see Section 4.2 for more detail).
