Ordering Information

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

Ω terminating resistor can be used next to the CLK pin. The total on-chip capacitance

is approximately 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

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).
