Test Content: Ref. IOL Ethernet Embedded MAU Conformance Test Suite test 14.1.7 TP-Model are defined as IEEE802.3 Fig 14-7. The specified loads are as Load 1 and Load 2. 180uH 115R 220uH 76.8R Load 2 (b). Test Result: Start of Idle with load 1 only 9 Start of Idle with load 2 only Start of Idle with load 1 through TP-Model 10 Start of Idle with load 2 through TP-Model (c). Discussion and Conclusion: The test passed. 11 Test (7). TD Differential Output Impedance(Return Loss) (a). Test Content: Ref. IOL Ethernet Embedded MAU Conformance Test Suite test 14.1.8 The test is only for reference resistance 100Ω. (b). Test Result: 40 35 30 10M Tx Returnloss dB 25 20 Limit 15 10 5 0 10 20 30 40 50 60 70 80 90 100 MHz Absolute value of Return Loss (c). Discussion and Conclusion: Since the absolute value of Return Loss are all above15dB, the test passed. 12 Test (8). Link Pulse Waveform with Specified Load (a). Test Content: Ref. IOL Ethernet Embedded MAU Conformance Test Suite test 14.1.10 TP-Model are defined as IEEE802.3 Fig 14-7. The specified loads are as Load 1 and Load 2. 180uH 115R 220uH 76.8R Load 2 (b).
