Evaluation Board User Guide
CHANNEL DIVIDER WINDOW
The channel divider window shown in Figure 18 is accessed by
clicking the appropriate channel divider. It is usually sufficient
to change only the divide ratio because the evaluation software
and the AD951x duty cycle correction ensure that the output
duty cycle remains very close to 50%.
You can also vary the phase offset by changing the Phase Offset
Bits setting. However, to have the new phase take effect, the
SYNC signal needs to be toggled by using the SYNC button
in the lower left corner of the main window.

LVPECL OUTPUT DRIVER WINDOW
The LVPECL Output 0 Settings window shown in Figure 20 is
accessed by clicking the OUT0 through OUT5 output driver
symbols on the right side of the main window (see Figure 19).
It is important to power down unused outputs on the evaluation
board because they can be a source of unwanted spurs.
