OSC_VCCP Power Filtering Diagram
OSC_VCC Requirement
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 OSC_VCC pins of the IXP45X/IXP46X network processors.
The grounds of both capacitors should be connected to the OSC_VSS supply pin. Both
capacitors should be located less than 0.5 inch away from the OSC_VCC pin and the
associated OSC_VSS pin.
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.
