Part Number: DP83867ERGZ-R-EVM
Hi,
We are using DP83867IRPAP and having problems with Ether 1000Base-T IEEE802.3 Compliance Test.
First, we tested with the custom board but the test have been failing as I said
in the following E2E thread and it's still haven't pass yet.
Then we bought DP83867ERGZ-R-EVM and tried the compliance test using the EVM.
But it also fails in the same section as the custom board.
Failed section is "Difference A,B Peak output voltage".
To test with the EVM, we used USB-2-MDIO and MSP-EXP430F5529LP to
access to the DP83867 registers.
First, we setuped the registers as mentioned in application note(SNLA239A).=>Test fails.
Then, we found the following video of compliance test at TI website,
and it was setting different registers which are not setuped in the
above application note, so we tried it.But the test failed.

Video:"Reduce design time with easy IEEE 802.3 compliance with TI's industrial
Ethernet Gigabit PHY"
I want to make me sure that which setting should we follow,
video or application note. Which one is correct? And why it's not the same setting?
Please take a look at attached image for register settings in the video.
Image may be NSFW.
Clik here to view.
I heard that DP83867EVM have passed all the section of compliance test.
But why our EVM can't pass the test?
We used following oscilloscope:
Oscilloscope Name: LCRY0439N69156 Model: SDA813ZI-A
Oscilloscope Serial #: LCRY0439N69156
Computer: LCRY0439N69156
Oscilloscope firmware version: 8.9.0.3 (Build 263624)
QualiPHY core version: 8.5.0.1 (Build 241419)
best regards,
