Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Tj−TSD allowed during error conditions only. It is assumed that this maximum temperature condition does not occur more than 1 hour
2. Mounted on a 1S2P (3 layer) test board with copper coverage of 25 percent for the signal layers and 90 percent copper coverage for the
3. Surges per EN61000−4−2, 1999 applied between RJ−45 and output ground and between adapter input and output ground of the evaluation
