LAYOUT GUIDELINE
Figure 3 shows a schematic example of the ICS840014I. An
example of LVCMOS termination is shown in this schematic.
Additional LVCMOS termination approaches are shown in
the LVCMOS Termination Application Note. In this example,
an 18pF parallel resonant 26.5625MHz crystal is used. The
FIGURE 3. ICS840014I SCHEMATIC EXAMPLE
C1=22pF and C2=22pF are recommended for frequency ac-
curacy. For different board layout, the C1 and C2 may be
slightly adjusted for optimizing frequency accuracy. 1K
pullup or pulldown resistors can be used for the logic control
input pins.
