Idaville LCC

[LisaXu]

Dear Intel Team:

we check the document <Idaville LCC Platform Design Guide (PDG)>, it shows I2C/SMBUS PCB trace length should be kept in below 30 inch. 

In my opinion, we ususally use ~3pF/inch for I2C trace length calculation, and 30inch just 90pF, it is highly below I2C standard 400pF, So could you share why you define the 30 inch PCB trace length restrict? 

Thanks!

Best Regards

Lisa
