Note s:
General Comment: For more information, refer to SATA II Revision 2.6 Specification, February, 2007.
General Comment: The load is 100 ohm differential for these parameters, unless otherw ise specified.
General Comment: To comply w ith the values presented in this table, refer to your local
Marvell representative for register settings.
1. 0.45-0.55 UI is the range w here the signal meets the minimum level.
2. Output Differential Amplitude and Pre-Emphasis are configurabile. See functional register description
for more details.
3. Defined for BR/10.
4. Defined for BR/500.
5. 0.5 UI is the point w here the signal meets the minimum level.
