Voltage and Current Specifications
The I/O buffer supply voltages are specified at the SoC package balls. The tolerances
shown in
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.
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.
