Datasheet

The I/O buffer supply voltage should be measured at the processor package pins. The 
tolerances shown in 

 are inclusive of all noise from DC up to 20 MHz. The 

voltage rails should be measured with a bandwidth limited oscilloscope with a roll-off of 
3 dB/decade above 20 MHz under all operating conditions. 

 indicates which 

supplies are connected directly to a voltage regulator or to a filtered voltage rail. For 
voltage rails that are connected to a filter, they should be measured at the input of the 
filter. If the recommended platform decoupling guidelines cannot be met, the system 
designer will have to make trade-offs between the voltage regulator out DC tolerance 
and the decoupling performances of the capacitor network to stay within the voltage 
tolerances listed below.
