ICS843011C
FEMTOCLOCKS CRYSTAL-TO-
3.3V LVPECL CLOCK GENERATOR
PRELIMINARY
APPLICATION SCHEMATIC
Figure 3A shows a schematic example of the ICS843011C.
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 ICS843011C P.C. board lay-
out. 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 capaci-
tors should be located as close as possible to the power pins.
The layout assumes that the board has clean analog power
ground plane.
