SATA-IO Confidential 60
2.15.2. RX-02 : Single-Ended Impedance (Obsolete)
2.15.2.1. Device/Host Expected Behavior
See section 7.2.2.4.2 of Serial ATA Revision 2.6.
• 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 a PHYRDY Interface Power State (see section 8.1. of
SATA Revision 2.6). The amplitude of a TDR pulse or excitation applied to a receiver shall not exceed
300mVpp (-6.48dBm 50 ohms) single ended.
• Z
s-eRX
measured to be at least 40 ohms (for products running at 1.5Gb/s)
Pass/Fail Criteria
• Both the minimum [RX-02a] and the maximum [RX-02b] results shall be captured
2.15.3. RX-03 : Gen2 (3Gb/s) Differential Mode Return Loss
2.15.3.1. Device/Host Expected Behavior
See section 7.2.2.4.3 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 (i.e. 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 a PHYRDY Interface Power State (see section 8.1. of
SATA Revision 2.6). The amplitude of a TDR pulse or excitation applied to a receiver shall not exceed
300mVpp (-6.48dBm 50 ohms) single ended.
• RL
