Hi,
Currently, My customer is doing the compliance test with DP83867IR on their custom board, but they have failed.
The following items are failed.
・1000 Base-T, Difference A,B Peak Output Voltage
・1000 Base-T, Point D Peak Output Voltage
・1000 Base-T, Point F Template Test
・1000 Base-T, Point H Template Test
・1000 Base-T, Transmitter Distortion
・10 Base-T, TP_IDL Template, with TPM (last bit CD0)
・10 Base-T, TP_IDL Template, with TPM (last bit CD1)
・10 Base-T, MAU Template
・10 Base-T, TP_IDL Template, without TPM (last bit CD1)
・10 Base-T, Peak Differential Voltage
And then, my customer have some questions.
1) They are referring SNLA239. They are setting the registers of DP83867IR following this Appendix B.
Is there any conflagration?
2)Is there any register to change the output level?
I think there is no such register and they need to confirm their hardware(Power supply, RBIAS, Layout....)
Also, please let me know if you find anything.
Best Regards,
Taka
