Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 13
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in

Note: It is important for the reliability of this device in any user environment that the junction temperature not exceed the T
specified in Table 17. Consequently, the effective junction to ambient thermal resistance (
maintained below the value determined by the formula:
Given that the values of T
achieve the desired
provided in Table 17), thermal resistance of the chosen adhesive (
circuit board (number of layers and size of the board). As a general guideline, this device will not need a heat sink if the board has 8 or more
layers AND the board size is larger than 4"x12" AND airflow in excess of 0.5 m/s is available. It is strongly recommended that users perform
their own thermal analysis for their own board and system design scenarios.
