Note s :
General Comment: For more inf ormation, ref er to SA TA II Revision 2.6 Specif ication, February, 2007.
General Comment: The load is 100 ohm dif f erential f or these parameters, unless otherw ise specif ied.
General Comment: To comply w ith the values presented in this table, ref er to your local
Marvell representative f or register settings.
1. 0.45-0.55 UI is the range w here the signal meets the minimum level.
2. Output Dif f erential A mplitude and Pre-Emphasis are conf igurabile. See f unctional register description
f or more details.
3. Def ined f or BR/10.
4. Def ined f or BR/500.
5. 0.5 UI is the point w here the signal meets the minimum level.
