VSC8601 Datasheet  
Design Considerations  
8.10  
High VDD33 and Low VDDIOMAC Supply  
Issue: If VDD33 is set to the maximum allowed 3.3 V supply and VDDIOMAC is set to  
the minimum allowed 3.3 V supply, the VSC8601 device can experience performance  
issues. These issues generally occur in a lab environment and not in typical  
applications.  
Implications: When VDDIOMAC is set to 3.3 V, VDD33 and VDDIOMAC cannot be  
sourced by two different 3.3 V supplies.  
Workaround: If using VDDIOMAC in 3.3 V mode, use the same 3.3 V source supply as  
the VDD33, using a proper filtering scheme. For more information, see VSC8601 Design  
and Layout Guide, which is available on the Vitesse Web site at www.vitesse.com.
