3.2. Termination of Differential Outputs
All differential outputs are to be tested into an 85  differential impedance transmission line. All output termination
resistors are fully integrated into the Si53119-A03A, no external components are required. Contact Silicon Labs
Support if 100  differential impedance support is needed.
