External Components / Crystal Selection

The ICS512 requires a 0.01µF decoupling capacitor to be connected between VDD and GND. It must be

connected close to the ICS512 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 and REF pins. The total on-chip

capacitance is approximately 15 pF, so a parallel resonant, fundamental mode crystal should be used. For

crystals with a specified load capacitance greater than 15 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

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).
