Regarding the voltage of the control signal of PCIE, the descriptions in the design guide and pin mux documentation are inconsistent
Both are correct. The pins are 1.8V level but 3.3V tolerance.
if the pins are 1.8V level,why use the 3.3V Isolator,and the description about those pins is pull up to 3.3V internally
Because the pins are 3.3v tolerance and 3.3v is for PCIe spec.
got it,thanks
