FEMTOCLOCKSCRYSTAL-TO-
3.3V LVPECL CLOCK GENERATOR
APPLICATION SCHEMATIC
Figure 3A shows a schematic example of the ICS843011.
An example of LVEPCL termination is shown in this sche-
matic. 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 optimizing frequency accuracy.

PC BOARD LAYOUT EXAMPLE
Figure 3B shows an example of ICS843011 P.C. board
layout. The crystal X1 footprint shown in this example al-
lows 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 pos-
sible to the power pins. The layout assumes that the board
has clean analog power ground plane.
