ICS502
LOCO™ PLL Clock Multiplier
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 33Ω 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
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).
