Can PCIE be used to receive LVDS data with imx6?

[Simon_Wu00]

Hi,

    I found that PCIE uses LVDS to transmit data.Can PCIE be used to receive LVDS data?

    I want to use dp to lvds chip to convert the DP signal, and use the PCIE of MX6 to receive it. Is this feasible?

Hi Simon

I am afraid it is not feasible, as i.MX6Q PCIe module works only with devices compatible with PCIe

specification :  https://en.wikipedia.org/wiki/PCI_Express

Hi igor,

If I write my own LVDS driver, can I use MIPI-CSI or PCIE interface to receive LVDS?

yes, if custom driver will comply with protocols defined in PCIe specification.

Also HCSL logic is used for PCIe, description can be found for example in
