Hi teams,
The HDMI IN test failed. The failure report indicated that the SCDC register was not cleared after the HDMI IN port was reconnected to 5V. The test result is shown in the image. could you please give some advices?

How are they connecting the DDC bus?
The SCDC registers are not part of the TMDS181, they are part of the HDMI sink. If the DDC bus is designed correctly, then the test failure is associated with the HDMI sink, not TMDS181.
Thanks
