IDT 89HPES16NT2 Data Sheet
Recommended Operating Temperature
Power Consumption
Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 14.
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
All power measurements assume that the part is mounted on a 10 layer printed circuit board with 0 LFM airflow.
Thermal Considerations
This section describes thermal considerations for the PES16NT2 (23mm2 BCG484 package). The data in Table 15 below contains information that
is relevant to the thermal performance of the PES16NT2 switch.
Note: The parameter θJA(eff) is not the absolute thermal resistance for the package as defined by JEDEC (JESD-51). Because resistance
can vary with the number of board layers, size of the board, and airflow, θJA(eff) is the effective thermal resistance. The values for effective
θJA given above are based on a 10-layer, standard height, full length (4.3”x12.2”) PCIe add-in card.
