©LeCroy CorporationObservable Results:• RJ measured (RJ meas ) at a maximum of 0.18 UI into a Laboratory Load before the Compliance InterconnectChannel (CIC) when measured using the specified JTF (for products running at 6Gb/s)• TJ measured at a maximum of (RJ meas ) + 0.34 UI into a Laboratory Load before the CIC when measuredusing the specified JTF (for products running at 6Gb/s)• TJ measured at a maximum of (RJ meas ) + 0.34 UI into a Laboratory Load after the CIC when measuredusing the specified JTF (for products running at 6Gb/s)Possible Problems: See PHY-01.LeCroy Corporation 40 SATA PHY, TSG, OOB LeCroy MOI rev 1.4 version 1.0
©LeCroy CorporationTest TSG-14 - Gen3 (6.0Gb/s) TX Maximum Differential Voltage AmplitudePurpose: To verify that the Gen3 (6.0Gb/s) maximum differential voltage of the PUT’s transmitter is within theconformance limits.References:[1] SATA Standard, 7.2.1, Table 31 – Transmitted Signal Requirements[2] Ibid, 7.2.2.2.7 – TX Differential Output Voltage[3] Ibid, 7.4.3.1 – Maximum Differential Voltage Amplitude (Gen3i)[4] SATA PRE-TEST MOI[5] SATA Interoperability Program Unified Test Document, 2.15.14Resource Requirements:Same as for TSG-01.See appendix A for details.Last Modification: March 25, 2009Discussion:Reference [1] specifies the Transmitted Signal conformance limits for SATA products. Reference [2]provides the definition this measurement. Reference [3] defines the measurement requirements for this test.Reference [4] describes the procedure for placing the PUT into BIST mode to generate the required test patterns.The maximum differential voltage amplitude at 6.0Gb/s is measured as the peak to peak voltage afteraveraging. The measurement is made over a 4 UI span with at least 500 averages. For this test an MFTP pattern isused.This test requirement is only applicable to products running at 6.0Gb/s.Test Setup:Same as for TSG-01.Test Procedure:The channels should be deskewed before performing this test. See Appendix A for details. The testprocedure then proceeds as follows:1) Open the QualiPHY SATA PHY, TSG, OOB test suite. See Appendix B for details.2) Select an appropriate configuration for a product running at 6.0Gb/s with TSG-14.3) Run the test.4) When prompted to produce a required test pattern set the product to generate that pattern. SeeAppendix C for details. Check the pattern on the oscilloscope to make sure it is correct. Press“OK” to continue.5) When the test completes, generate a report. Observe the results for TSG-14 VDiffTXMax in thereport.Observable Results:The maximum differential voltage VDiffTXMax shall be at most 900mV.Possible Problems: See PHY-01.LeCroy Corporation 41 SATA PHY, TSG, OOB LeCroy MOI rev 1.4 version 1.0
