General Operating Conditions
Table 2.
Recommended Operating Conditions
a
a.
Sustained operation of the device at conditions exceeding these values, even if they are within the absolute maximum rating limits, might
result in permanent damage. Device functionality to stated DC and AC limits is not guaranteed, if conditions exceed recommended oper-
ating conditions.
See
Section 4.2.2
for voltage ramp and sequencing recommendations.
Operation with internal voltage regulator control of PNP pass transistor may exceed this range due to 82571EB process skew tracking.
1000BASE-T designs require thermal management (heatsink and/or forced air flow) to achieve 0° to 55° C operation. Increased thermal
management can increase this temperature range to 0° to 70° C. Applications using the SERDES interface are rated for 0° to 70° C without
thermal management.
