... The schematic in Figure 20 illustrates a termination scheme for 50Ω series termination and a 100Ω twisted pair cable. Note RCM is the common mode termination to allow measurement of V and should not be too small since it CM loads the ISL59311; a little over a 100Ω is recommended for RCM. + TWISTED 50Ω 50Ω ...

... Power Dissipation Calculation When switching at high speeds, or driving heavy loads, the ISL59311 drive capability is ultimately limited by the rise in die temperature brought about by internal power dissipation. For reliable operation die temperature must be kept below T (+125°C necessary to calculate the power dissipation for a given application prior to selecting package type ...
