Specifications
SATA-IO Confidential 41
Pass/Fail Criteria
For an internal SATA and eSATA cable:
• Cable Absolute Differential Impedance 100 Ohms ±10%
2.7.3. SI-03 : Cable Pair Matching
2.7.3.1. Cable Assembly Expected Behavior
See section 6.5.1.1, Table 16 of the Serial ATA Revision 2.6 specification.
The test shall be performed on one end of the cable assembly, for each differential pair of the assembly.
Measurement Requirements
• See section 6.5.2.4, Table 21, Procedure P3 of the Serial ATA Revision 2.6 specification.
• This test is normative for internal SATA cables and informative for eSATA cables.
• For an internal SATA and eSATA cable:
o After completing the common procedures (and before doing the measurement) the instrument rise
time shall be set or the results filtered for a minimum of 55 ps to a maximum of 70 ps (20-80%)
system rise time. The system rise time shall be set as close to 70 ps (20-80%) as practical.
Pass/Fail Criteria
For an internal SATA and eSATA cable:
• Cable Pair Matching Impedance ±5 Ohms
2.7.4. SI-04 : Common Mode Impedance
2.7.4.1. Cable Assembly Expected Behavior
See section 6.3.5.1, Table 16 of the Serial ATA Revision 2.6 specification.
Measurement Requirements
• This test is normative for internal SATA cables and informative for eSATA cables.
• For an internal SATA and eSATA cable:
See section 6.5.2.4, Table 21, Procedure P4 of the Serial ATA Revision 2.6 specification.
