Hi team,
My customer is checking this device, and he found VOL and VIL do not meet the I2C spec.
VOL max＝0.17×VccA (0.4V officially)
VIL max＝0.082×VccA (0.3xVdd officailly)
Do we need to follow the datasheet or official specs? And why there are differences?
Best,
Zeming
Hi Zeming,
Thank you for you sharing.
For the connector side of SCL and SDA(SCL_CON&SDA_CON), it should be the same with what your share.
Our datasheet:
I2C spec:
Our datasheet:
I2C spec:
And our datasheet about HDMI side of SCL and SDA(SCL_SYS&SDA_SYS), it seems to smaller than the I2C spec, so it also can conforms the I2C spec, but why are they different, sorry, I do not know the reason.
Just like I told to you before, this is a old device, what I can support is only from the datasheet, so sorry, I can not explain why they are different to you, but I guess it should not influent your application.
Best Regards,
Kuno
