Part Number: TPD12S016
We are using "TPD12S016PWR" ESD IC with HDMI Transmitter "SiI9022ACNU" IC Combination in our Design. While testing HDMI Interface we are facing DDC EDID read Error.After removing the ESD IC and done direct wiring from HDMI Transmitter IC to HDMI Connector, it is working without any issues(EDID Read passes).We are suspecting that with ESD Chip is not meeting the I2C timing specification.What are the timing which TPD12S016PWR" is violating?Could you please suggest how to solve the above mentioned issue.

Please see my answers in line.
What else do you have connected to the I2C line? Ans: We have connected only the HDMI Transmitter to the I2C lines. No other devices are connected to I2C linesCould you send a schematic Ans: I have shared the Schematics of HDMI Transmitter"SiI9022ACNU" and ESD Chip "TPD12S016PWR" section.And a two waveforms of the signal, one with the ESD device connected and one without it.Ans: Yes I have shared the two waveforms of the signal's.one is with ESD(DDC EDID read Error) and another one is without ESD(EDID Read passes).
