1. The input coupling capacitor must be set accordingly for lower data rates.
2. Turning on input trace equalization will reduce jitter in most applications.
3. Rise/Fall time measured between 20ꢀ and 80ꢀ.
4. Single-ended into 75Ω external load.
5. Calculated as the actual positive bit-width compared to the expected positive bit-width using a 1010 pattern.
6. ORL depends on board design. The GS2988 achieves this specification on Semtech's evaluation boards.
