HDMI I2C Voltage

Just wanted to confirm the signaling voltage min/max (VIL, VIH) for the I2C HDMI signals?

We were looking here at the data sheet: http://developer.nvidia.com/embedded/dlc/jetson-tx2-module-data-sheet-1-1

We’re assuming it’s table 61 in this data sheet, which specifies .25 * 1.8v, so < .45v as the threshold for low?
We just wanted to make sure that table 61 applies to I2C pads as well, and there’s not another table somewhere with different thresholds.

Thanks

Yes, that is for OD pins including I2C. BTW, I2C of HDMI is 3.3V on Tegra side.

OK, thanks for clarifying!
