ZERO DELAY CLOCK GENERATOR
PRELIMINARY
LAYOUT GUIDELINE
The schematic of the ICS874S02I layout example is shown in
Figure 5A. The ICS874S02I recommended PCB board layout
for this example is shown in Figure 5B. This layout example is
used as a general guideline. The layout in the actual system will
depend on the selected component types and the density of
the P.C. board.

LVDS DRIVER TERMINATION
A general LVDS interface is shown in Figure 4. In a 100

differential transmission line environment, LVDS drivers re-
quire a matched load termination of 100
Ω across near the
