FIGURE 3. ICS840031I APPLICATION SCHEMATIC EXAMPLE
APPLICATION SCHEMATIC EXAMPLE
Figure 3 shows a schematic example of the ICS840031I. In this
example, a series termination, one of LVCMOS termination ap-
proaches, is shown. Additional LVCMOS termination approaches
are shown in the LVCMOS Termination Application Note. In this
example, an 18pF parallel resonant crystal is used.The C1=22pF
and C2=33pF are approximate values for frequency accuracy.
The C1 and C2 may be slightly adjusted for optimizing frequency
accuracy.
