Notes:
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. Total jitter is defined as TJ = (14 * RJ
σ
) + DJ w here Rj
σ
is random jitter.
2. Output Differential Amplitude and Pre-Emphasis are configurabile. See functional register description
for more details.
