ICS514
LOCO™ PLL Clock Generator
External Components / Crystal Selection
The ICS514 requires a 0.01µF decoupling capacitor to be connected between VDD and GND. It must be
connected close to the ICS514 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 and REF pins. The total on-chip
capacitance is approximately 12 pF, so a parallel resonant, fundamental mode crystal should be used. For
crystals with a specified load capacitance greater than 12 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-12)*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).
