ICS843051 Data Sheet
FEMTOCLOCK CRYSTAL-TO-3.3V LVPECL CLOCK GENERATOR
Schematic Example
Figure 5A shows a schematic example of the ICS843051. 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 crystal is used. The C1 = 27pF and C2 = 33pF are
recommended for frequency accuracy. The C1 and C2 values may be
slightly adjusted for optimizing frequency accuracy.

PC Board Layout Example
Figure 5B shows an example of ICS843051 P.C. board layout. The
crystal X1 footprint shown in this example allows installation of either
surface mount HC49S or through-hole HC49 package. 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.
