From datasheet of JetsonAGXXavierSeriesDatasheet_DS09654001v1.1，in open drain pin, I2C output low voltage(Iol=3.3mA) is 0.3xVDD,but output low voltage(Iol=1mA) is 0.15xVDD.We use I2C2_CLK/Data as I2C communicate with a device,which is pulled up 2K to 1.8V,and which paramater we should choose as consideration of Vol(0.3xVDD or 0.15xVDD) ?

Look foward to your reply！
Hi
For i2c bus, the max of Vol is 0.3*VDD at 3.3mA sink current.
Thank you for your reply.
When the sink current of i2c bus is 1.8mA(pull up 1K to power 1.8V),we should choose which max value of Vol ?
0.3 x VDD is better for that.
Got it！Thanks.
