Specifications

SATA-IO Confidential 51
• See section 7.4.23 of Serial ATA Revision 2.6.
Measurement Requirements
• This test requirement is only applicable to products running at 1.5Gb/s. For products which support 3Gb/s,
this test is not required.
• Testing of this requirement must be completed during transmission of the Mid Frequency Test Pattern
(MFTP), The amplitude of a TDR pulse or excitation applied to an active transmitter shall not exceed
139mVpp (-13.2dBm 50 ohms) single ended.
• Z
s-eTX
measured to be at least 40 ohms (for products running at 1.5Gb/s)
Pass/Fail Criteria
• Both the minimum [TX-02a] and the maximum [TX-02b] results shall be captured
2.13.3. TX-03 : Gen2 (3Gb/s) Differential Mode Return Loss
2.13.3.1. Device/Host Expected Behavior
See section 7.2.2.2.3 of Serial ATA Revision 2.6+.
• See section 7.4.10 of Serial ATA Revision 2.6.
Measurement Requirements
• Calibrate to the end of the SMA cables, but do NOT include (de-embed) the SMA to SATA PCB and the
SATA connector, so the board and the SATA connector are INCLUDED with the product measurement.
• This test requirement is only applicable to products running at 3Gb/s.
• Testing of this requirement must be completed during transmission of the Mid Frequency Test Pattern
(MFTP), The amplitude of a TDR pulse or excitation applied to an active transmitter shall not exceed
139mVpp (-13.2dBm 50 ohms) single ended.
