1)Does the I2C of the LMK05318B fully comply with all the features of the I2C specification? When we test the I2C signal waveform, when we find that that the results are not consistent with the datasheet, is the datasheet the correct one or theC specification the correct one?
The data sheet says that the minimum value for th(start) is 0.6us and the maximum value for th(SDA) is 0.9us. Are these two values following the data sheet when I2C is operating in standard mode, i.e. 100kHz?Or follow the standard mode as defined in the I2C specification v2.1?
2)At this point we actually test the RH(start) time for about 3.765us. The following waveform is sufficient if you follow the minimum value of 0.6us written by the datasheet.However, if the minimum value written in the I2C protocol specification is 4.0us, it is not sufficient.
How can the LMK05318B IC operate if the minimum value written in the datasheet is met but the minimum value required by the I2C protocol specification standard mode is not met?
3)Currently, we actually test the tH(SDA) for about 2.053 us. The following waveform is sufficient if you write a maximum value of 3.45 us in standard mode according to the I2C protocol specification.
However, if the maximum value written in the datasheet is 0.9us, this is not the case.
What is the impact on the operation of the LMK05318B IC if the I2C protocol specification standard mode requirement is met but the maximum value written in the datasheet is not met?
