External Components / Crystal Selection
The ICS504 requires a 0.01F decoupling capacitor to be connected between VDD and GND. It must be
connected close to the ICS504 to minimize lead inductance. No external power supply filtering is required
for this device. A 33
terminating resistor can be used next to the CLK pin. The total on-chip crystal
capacitance is approximately 13 pF, and a parallel resonant, fundamental mode crystal should be used. For
crystals with a specified load capacitance greater than 13 pF, crystal capacitors should 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-13)*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).
