DP83867CS: About 1000BASE-T JITTER test

Part Number: DP83867CS
Other Parts Discussed in Thread: DP83867E


I would like to do a 1000BASE-T JITTER test on the DP83867E SGMII EVM evaluation board.
I found a related thread on this subject on the E2E community,I didn't know if it was resolved.
Please tell me the following points.


2.Excerpt from the above E2E Community
In the above E2E Community content, there was an answer that TX_TCLK is not supported.
I discuss this issue internally and we realized 867 does not support TX_TCLK for compliance test.
Hillman Lin
Yes, you are correct on the first statement TX_TCLK cannot be used in all the Jitter test in compliance tests.
Hillman Lin

Please tell me about the 1000BASE-T JITTER test.
The test below uses TX_TCLK to perform compliance testing.
Is it possible to perform the following tests?

1.Test items
(1)MASTER mode JTxOut (w/ TX_TCLK)
(2)Jitter MASTER Filtered (w/ TX_TCLK)
(3)Jitter MASTER Unfiltered (w/ TX_TCLK)

(4)SLAVE mode JTxOut (w/ TX_TCLK)
(5)Jitter SLAVE Filtered (w/ TX_TCLK)
(6)Jitter SLAVE Unfiltered (w/ TX_TCLK)

Please let me know why the DP83867 only doesn't support TX_TCLK.
