Hi!

I am using T1042 and using 1st four Lanes of SerDes as PCIe. These PCIe Lanes are connected to PCIe switch which communicate with i/o volatge of 3.3V. I am confused with voltage compatibility.

can i connect this PCIe switch directly to SerDes pins or i need any voltage converter?

Thank You

The T1042 must be connected so that its Data Sheet requirements and specifications were met.

For the SerDes PCIe inputs characteristics please refer to the section "3.22.4.3 PCI Express DC physical layer receiver specifications".
