2.14.12. TSG-12 : Gen2 (3Gb/s) DJ at Connector, Clock to Data, f
BAUD
/500
2.14.12.1. Device/Host Expected Behavior
See sections 7.2.2.3.12 and 7.3 of Serial ATA Revision 2.6.
• See sections 7.4.6 and 7.4.8 of Serial ATA Revision 2.6.
Measurement Requirements
• This test requirement is only applicable to products running at 3Gb/s.
• The loop damping factor for the reference PLLs is required to be 0.707.
• There are several different patterns defined within the specification and are intended to be used to verify this
requirement. In order to ensure efficient test time of products within the Interoperability Testing, testing of this
requirement will be limited to the following patterns as defined in the SATA Revision 2.6 specification: High
Frequency Test Pattern (HFTP) [TSG-12a], and Lone Bit Pattern (LBP) [TSG-12b]. It is optional to
additionally test using the Simultaneous Switching Outputs Pattern (SSOP) [TSG-12c] as a third pattern.
• DJ measured at a maximum of 0.19 UI when measured at f
BAUD
/500 (for products running at 3Gb/s)
Pass/Fail Criteria
2.15. Phy Receiver Requirements
During the testing execution for all RX test requirements, it is essential that the product under test be able to complete
an initial OOB sequence through the device COMWAKE. This is to allow product calibration to occur prior to and/or
during the initial power on and detect sequences.
2.15.1. RX-01 : Pair Differential Impedance
2.15.1.1. Device/Host Expected Behavior
See section 7.2.2.4.1 of Serial ATA Revision 2.6.
• See section 7.4.22 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.
• Verify that both the minimum [RX-01a] and maximum [RX-01b] results for the pair differential impedance
measured between 85 ohms and 115 ohms (for products running at 1.5Gb/s)
Pass/Fail Criteria
• NOTE : The verification of this result may not be required. If a product which supports 1.5Gb/s product
passes RX-06, then it is not required that this test be verified. This result must be verified for a 1.5Gb/s
product if it fails RX-06.
