IDT 89HPES8T5 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 13
(and also listed below).
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
Table 13 (and also listed below).
Thermal Considerations
This section describes thermal considerations for the PES8T5 (19mm2 BCG324 package). The data in Table 16 below contains information that is
relevant to the thermal performance of the PES8T5 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.
