(2) No heat sink or airflow was assumed for these estimations. Depending on the application, a heat sink, faster airflow, and/or reduced ambient temperature (<85 C) may be required in order to meet the maximum junction temperature specification per the Recommended Operating Conditions. 7.5 Electrical Characteristics over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT POWER CONSUMPTION WChannel Power Consumption Per Active Channel Active mode with CTLE, Tx FIR, full DFE and Crosspoint enabled.
