FIGURE 4A. APPLICATION SCHEMATIC EXAMPLE
APPLICATION SCHEMATIC
Figure 4A provides a schematic example of ICS844031I. In this
example, an 18 pF parallel resonant crystal is used. The
C1=22pF and C2=22pF are recommended for frequency. The
C1 and C2 values may be slightly adjusted for optimizing fre-
quency accuracy. At least one decoupling capacitor near the
power pin is required. Suggested value range is from 0.01uF to
0.1uF. Other filter type can be added depending on the system
power supply noise type.
FIGURE 4B. ICS843001 PC BOARD LAYOUT EXAMPLE
PC BOARD LAYOUT EXAMPLE
Figure 4B shows an example of ICS844031I P.C. board layout.
The crystal X1 footprint shown in this example allows installa-
tion of either surface mount HC49S or through-hole HC49 pack-
age.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.
