AD9300 APPLICAT IONS
T o ensure optimum performance from circuits using the AD9300,
it is important to follow a few basic rules that apply to all high
speed devices.
A large, low-impedance ground plane under the AD9300 is
critical. Generally, GROUND and GROUND RET URN con-
nections should be connected solidly to this plane. GROUND
pin connections are signal isolation grounds that are not

connected internally; they can be left unconnected, but there
may be some degradation in crosstalk rejection. GROUND RE-
T URN, on the other hand, serves as the internal ground refer-
ence for the AD9300 and,
without exception,
should be
connected to the ground plane

(the interval between the 50% point of the
ENABLE high-to-low transition and the instant the output
becomes a high impedance).
For applications such as driving cables (see Figure 2), output
buffers are recommended.
It is recommended that the AD9300 be soldered directly into
circuit boards rather than using socket assemblies. If sockets
must be used, individual pin sockets are preferred rather than a
socket assembly. A second requirement for proper high speed
design involves decoupling the power supply and
internal bias supply lines from ground to improve noise immu-
nity. Chip capacitors are recommended for connecting 0.1
