Hi,
What is the tolerance for the 2nF capacitor used on CEXT pin2? What about the temp rating? X7R, C0G?
I also checked the evaluation board schematic and it uses a 100nF capacitor. Which is correct, the datasheet or reference design?

Hi Jeevan,
Please use the datasheet value of 2nF. The capacitor should have a tolerance of 10% or less and will have a maximum of 3.3V on it. Temperature rating should be equal to that of the PHY or of your application. There is no requirement for capacitor type.
Thanks,
David
