External Components / Crystal Selection
The ICS525-01 requires two 0.01F decoupling capacitors to be connected between VDD and GND, one
on each side of the chip. They must be connected close to the ICS525-01 to minimize lead inductance.
No external power supply filtering is required for this device. A 33
terminating resistor can be used next
to the CLK and REF pins. The total on-chip capacitance for a crystal is approximately 16 pF, so a parallel
resonant, fundamental mode crystal with this value of load (correlation) capacitance should be used. For
crystals with a specified load capacitance greater than 16 pF, crystal capacitors may 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-16)*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).
