ADV7511W DDCSDA/SCL pull high Voltage

Dear ADI support Team,

 

In ADV7511W hardware user guide, it describes that the DDCSDA and DDCSCL pins should be connected to the HDMI connector. A pull-up resistor of 1.5 kΩ to 2kΩ (+/-10%) to HDMI +5V is required for each of these signals.

 

For my current design, I add one HDMI ESD at output side of ADV7511W and pull most output signal to VLV (3.3V) rather than 5V.

 

Will there be any risk to connect ADV7511W's output like this ? 

 

 

Thanks very much!
