LAYOUT SUGGESTIONS
Designs that use the AD9048 or any other high speed device
must follow some basic layout rules to ensure optimum
performance.
The first requirement is to have a large, low impedance ground
plane under and around the converter. If the system uses sepa-
rate analog and digital grounds, both should be solidly con-
nected together, and to the ground plane, as closely to the
AD9048 as practical to avoid ground loop currents.
Ceramic 0.1
μ
F decoupling capacitors should be placed as closely
as possible to the supply pins of the AD9048. For decoupling
low frequency signals, use 10
μ
F tantalum capacitors, also con-
nected as closely as practical to voltage supply pins.
Within the AD9048, reference currents may vary because of
coupling between the clock and input signals. As a result, it is
important that the ends of the reference ladder, R
T
(Pin 18) and
R
B
(Pin 28), be connected to low impedances (as measured
from ground).
If the AD9048 is being used in a circuit in which the reference
is not varied, a bypass capacitor to ground is strongly recom-
mended. In applications that use varying references, they must
be driven from a low impedance source.
