TDA4VM: query for PCIe configuration and its usage in TDA4

Minwoo Song

Part Number: TDA4VM

Hi TI,

I have a question for TDA4 PCIe confiuration with other board.

I want to make the connected system between TDA4 HW platform and the other HW platform using PCIe.

At this time, to make 2 Lane PCIe interface, Can I use below configuration in TDA4 ?

- to make 2 lane PCIe interface

- one lane is from SERDES2 pin-groups

- the other one lane isfrom SERDES3 pin-groups

- its clock is from SERDES3 pin-group

Like this, when I configured PCIe lanes from different SERDES group, is it possible mehod to make ?

Thanks

Any single PCIe interface should use a single SERDES pin group. This includes REFCLK. Interfaces cannot extend across multiple SERDES pin groups.

Hi Robert Eschler,

It's a clear answer of yours.

Thanks !
