Hi,
I wanted to know what the transitions will look like when we probe the m_axis_lnk_tx_lane data lines of DisplayPort TX IP, when the Video PHY is set to work in the "Standard Operation" as suggested by bits [4:2] of TX Control (TXC) - 0x0070 register of the Video PHY. The kind of waveform I could probe is attached herewith. What does this pattern indicate?
Thanks in advance.

Hi @amrutham,
What does this pattern indicate?
Nothing... I am not sure about what you are expecting to see... DP is using 8b/10b encoding. So you will see 8b/10b encoded data...

Hi Florent,
Thank you for the response. The data to the 8b/10b encoder is 00000000. So like you said this must be the encoded data. Thank you for clarifying the doubt.
