LAYOUT GUIDELINE
Figure 5 shows a schematic example of the ICS843004-01. An
example of LVEPCL termination is shown in this schematic.
Additional LVPECL termination approaches are shown in the
LVPECL Termination Application Note. In this example, an 18pF

parallel resonant 25MHz crystal is used. The C1=27pF and
C2=33pF are recommended for frequency accuracy. For different
board layout, the C1 and C2 may be slightly adjusted for optimizing
frequency accuracy.
