External Components / Crystal Selection
The ICS502 requires a 0.01µF decoupling capacitor to be connected between VDD and GND. It must be
connected close to the ICS502 to minimize lead inductance. No external power supply filtering is required for this
device. A 33
13 pF, so 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 = (C L -13)*2, where C L
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).
