Figure 3Ashows a schematic example of the ICS843011. 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 18 pF
parallel resonant 26.5625MHz crystal is used for generating
106.25MHz output frequency. The C1 = 27pF and C2 = 33pF
are recommended for frequency accuracy. For different board
layout, the C1 and C2 values may be slightly adjusted for opti-
mizing frequency accuracy.

Figure 3B shows an example of ICS843011 P.C. board layout.
The crystal X1 footprint shown in this example allows installa-
tion of either surface mount HC49S or through-hole HC49 pack-
age. The footprints of other components in this example are listed
in the Table 6. There should be at least one decoupling capacitor
per power pin. The decoupling capacitors should be located as
close as possible to the power pins. The layout assumes that
the board has clean analog power ground plane.
