TDA4VM: How to optimize the PCIe eye diagram ?

Part Number: TDA4VM

Hi ,

We develop the PCIe communicate feature between two TDA4 in QNX and test the eye diagram, result as following.

/cfs-file/__key/communityserver-discussions-components-files/791/PCIe_5F00_Eye_5F00_Pattern_5F00_20220228.pdf

According the eyediagram, only SOC1 RX0 works fine, the others all has the same problem that EyeHeight is too small.

Please provide a register to configure to increase the value of EyeHeight and improve the eye diagram, thanks.
