Evaluation Board User Guide
QUICK START GUIDE TO THE AD9516 PLL
When the evaluation software is installed, the evaluation board
is connected, and the software is loaded, use the following steps
to configure and lock the PLL. These steps assume that the input
signal is present, the evaluation board has not been modified,
and that the PLL loop filter is suitable for the user’s application.
This quick start guide covers only simple PLL operation to
start the PLL. See the AD9516 data sheet and Evaluation
Software Components section for a detailed explanation
of the various AD9516 features.
The following case is an example for the AD9516-3 using the
values in Table 1.

Turn the PLL on by selecting Normal Op from the PLL
MODE box found at the top of the main window (see
Figure 8).
Enter the intended reference input frequency (in
megahertz) in the REF 1 (MHz) box at the upper left
corner of the main window.
Click the triangular buffer symbol immediately to the right
of the input reference frequency (see Figure 4) boxes to load
the Reference Input Control window shown in Figure 5.
Turn the REF1 reference input buffer on by selecting the
Enable REF1 check box, and then clicking OK.

When the window closes, the WRITE button under the
REGISTER W/R section in the main window blinks red.
This indicates there are settings that have not been loaded
to the AD9516 evaluation board. Click the blinking red
WRITE button to load these settings to the evaluation
board.
Select the VCO as the input to the clock distribution
circuitry by clicking the mux symbol that is located
immediately to the right of the VCO (MHz) box (see
Figure 6).
When the VCO is selected, the border of the VCO (MHz)
box changes from gray to black. The current VCO
frequency is shown in the VCO (MHz) box.
