Figure 5
shows a schematic example for ICS843004I-04. In
this example, the input is a 19.44MHz parallel resonant crystal
with load capacitor CL=18pF. The 22pF frequency fine tuning
capacitors are used C1 and C2. This example also shows general
logic control input handling. For decoupling capacitors, it is

recommended to have one decouple capacitor per power pin.
Each decoupling capacitor should be located as close as
possible to the power pin. The low pass filter R2, C3 and C4
should also be located as close to the V
CCA
pin as possible.
