PLL Section
The AD9510 on-chip PLL consists of a programmable reference divider, a programmable feedback divider, a phase-frequency detector,
and charge pump. All are represented as list boxes in the PLL section (Figure 16) of the main interface window of the software.
Additionally, the PLL section includes list boxes for PLL reference settings and one for the status pin output.

When the input frequencies and the divider values are entered, the calculated internal frequencies are displayed. If the frequencies match,
they appear in blue; otherwise, they appear in red.
