TUSB7340: Drive strength of PCIE_TXN, P

user5600742

Part Number: TUSB7340

I could not find how to change drive strength of PCIE_TX.

Can I change drive strength or slew rate?

Please refer to section 7.3.1.1, you can change output SWING and De-emphasis through the De-Emphasis and Swing Control Register.

Thanks

Hi avid

I knew these parameters. I took these parameters as ethernet lines.

Are these really related to PCIE lines?

I'm asking for PCIE_TX lines, connected to micro-processor.

Unfortunately, the control is only provided on the USB side, not on the PCIe side.

Thanks
David
