Requirements
To reduce voltage-supply noise on the analog sections of the IXP45X/IXP46X network processors,
the phase-lock loop circuits (V
V
The filter circuits for each supply are shown in the following sections.
V
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.
