A single 170-nF capacitor must be connected between the V
pin of the IXP42X product line and IXC1100 control plane processors. This capacitor
value provides both bypass and filtering.
When 170 nF is an inconvenient size, capacitor values between 150 nF to 200 nF could
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.

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 33 MHz — must be connected to
both of the V
processors.
