External Components / Crystal Selection
The ICS307 require a 0.01μF decoupling capacitor to be connected between VDD and GND. It must be
connected close to the ICS307 to minimize lead inductance. A 33
terminating resistor can be used in
series with the CLK1 and CLK2 outputs. A parallel resonant, fundamental mode crystal with a load
(correlation) capacitance of C should be used, where C is the value calculated from Table 4. For crystals
with a specified load capacitance greater than C, additional crystal capacitors may be connected from each
of the pins X1 and X2 to Ground as shown in the Block Diagram on page 1. The value (in pF) of these
crystal caps should be = (CL-C)*2, where CL is the crystal load capacitance in pF. These external
capacitors are only required for applications where the exact frequency is critical. For a clock input,
connect to X1 and leave X2 unconnected (no capacitors on either pin).
