7. Electrical Specifications
7.1
Operating Conditions
This chapter describes 82598 DC and AC (timing) electrical characteristics. This includes maximum
rating, recommended operating conditions, power sequencing requirements, and DC and AC timing
specifications. DC and AC characteristics include generic digital 3.3 V dc IO specification, as well as
other specifications supported by the device.

Note: Ratings in this table are those beyond which permanent device damage is likely to occur. These values should not be
used as the limits for normal device operation. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
Recommended operation conditions require accuracy of power supply of +/-5% relative to the nominal voltage
Vi/Vo of 3.3 V dc compatible I/Os maximum should be the minimum of 4.6 V dc or (VCC3P3+0.5).
