ICS525-02 Output Divider and Maximum Output Frequency Table
External Components / Crystal Selection
The ICS525 requires two 0.01μF decoupling capacitors to be connected between VDD and GND, one on
each side of the chip. They must be connected close to the ICS525 to minimize lead inductance. No
external power supply filtering is required for this device. A 33
series terminating resistor can be used
next to the CLK and REF pins. The approximate total on-chip capacitance for a crystal is 16pF, so a
parallel resonant, fundamental mode crystal with this value of load (correlation) capacitance should be
used. For example, using the ICS525-01 with crystals having 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).
The ICS525-02 is only offered in the
industrial temperature range.
