Hi team,

for I2C Data setup time, could you please confirm the unit (ns? or us?) and the spec (560ns? or 0.56us?)

Hi team,

Could you please check on bit error rate expected, if it should be Bit error rate≥10^-10 or Bit error rate≤10^-10?

Hi Youhei,

I reviewed and compared between different datasheet. It seems this is just a parameter when they measured the data. In my opinion, it should be BER <= 10e-12.

Regarding to the setup hold time, The I2CV is fairly standardize specs. I don't think 560ps is a valid number. Most of other datasheet doesn't specify the typical value. I would think the value is 560ns not .56ns.
