A parallel combination of a 10-nF capacitor (for bypass) and a 200-nF capacitor (for a first-order
filter with a cut-off frequency below 30 MHz) must be connected to the V
IXP45X/IXP46X network processors.
The ground of both capacitors should be connected to the nearest V
should be located less than 0.5 inch away from the V
order to achieve the 200-nF capacitance, a parallel combination of two 100-nF capacitors may be
used as long as the capacitors are placed directly beside each other.

V
A single, 170-nF capacitor must be connected between the V
the IXP45X/IXP46X network processors. This capacitor value provides both bypass and filtering.
When 170 nF is an inconvenient size, capacitor values between 150 nF to 200 nF can be used with
little adverse effects, assuming that the effective series resistance of the 200-nF capacitor is under
50 mΩ .
In order to achieve a 200-nF capacitance, a parallel combination of two 100-nF capacitors may be
used as long as the capacitors are placed directly beside each other. V
