LVDS/CMOS OUTPUT DRIVER WINDOW LVDS/CMOS OUTPUT DELAY WINDOW
The LVDS/CMOS Output 6 Settings window shown
in Figure 21 is accessed by clicking the OUT6 through
OUT9 output driver symbols on the lower right side of
the main window.
The Output 6 Delay window shown in Figure 22 is accessed
by clicking the
ΔT OUT 6
button on the right of the main
screen. To access any other output delay window, click the
appropriate
ΔT OUT x button.
Selecting the various combinations of ramp current and
ramp capacitors changes the amount of delay for that driver,
and the estimated amount of delay is shown in the right half
of the window. The feature is described in detail in the AD951x
data sheet.

The Serial I/O section of this window is a convenient way to
read and write registers directly.
If LVDS mode is selected, the bottom (CMOS) portion of the
window is grayed out. Likewise, if CMOS mode is selected, the
top (LVDS) portion of the window is grayed out.

It is important to power down unused outputs on the evaluation
board because they can be a major source of unwanted spurs.
This is especially true of the CMOS drivers.
