Hi Sir,
The page 1 of the data sheet is described as "noise filter on SCL / SDA inputs."
I wanna know more about it.
Could you tell me the circuit configuration and the values of this noise filter?
Thanks.

The I²C specification requires that for fast-mode devices, spikes shorter than 50 ns are filtered out. This is that filter.
Hi Clemens,
I wanna know more about this filter.
May I get details from you?
Thanks a lot.
Hi Frank,
The filter in the schematic is just a 50ns deglitch filter. As Clemens said this is just to match the I2C spec. Typically these filters are just low pass filters with a 50ns time constant.
Best,
Chris
