©LeCroy CorporationTest TSG-12 – Gen2 (3.0Gb/s) DJ at Connector, Clock to Data, f BAUD /500 JTF DefinedPurpose: To verify that the Gen2 (3.0Gb/s) DJ at Connector (Clock to Data, f BAUD /500) of the PUT’s transmitter iswithin the conformance limits.References:[1] SATA Standard, 7.2.1, Table 31 – Transmitted Signal Requirements[2] Ibid, 7.2.22.18 – Clock-to-Data Transmit Jitter (Gen1i, Gen1m, Gen1x, Gen2i, Gen2m, Gen2x,Gen3i)[3] Ibid, 7.3.2 – Reference Clock Definition[4] Ibid, 7.4.8 – Jitter Measurements[5] SATA PRE-TEST MOI[6] SATA Interoperability Program Unified Test Document, 2.15.12Resource 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. This specificationincludes conformance limits for the DJ at Connector (Clock to Data, f BAUD /500). Reference [2] provides thedefinition of this term for the purposes of SATA testing. Reference [3] defines the measurement requirements forthis test. Reference [5] describes the procedure for placing the PUT into BIST mode to generate the required testpatterns.The Unified Test document specifies that this test should be made with HFTP and LBP, and if time permitsshould also be made with SSOP. The test is performed by making an edge to reference jitter measurement. A PLLmeeting the Jitter Transfer Function requirements in [3] is used to recover the clock. Follow the procedure inAppendix E to set the PLL appropriately. A 500µs acquisition is used for this test corresponding to 1.5 million UI,as described in TSG-01.This test requirement is only applicable to products running at 3.0Gb/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 3.0Gb/s with TSG-12 selected andthe PLL natural frequency and damping set correctly (see Appendix E).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-12 in the report. Thevalues for DJ, f BAUD /500 are reported for HFTP and separately for LBP and SSOP. TSG-12passes only if both the HFTP and LBP values pass.Observable Results:The DJ shall be at most 0.19UI when measured at f BAUD /500 for products running at 3.0Gb/s.LeCroy Corporation 37 SATA PHY, TSG, OOB LeCroy MOI rev 1.4 version 1.0
