SN65DP159: SN65DP159 Display Port link training fial issue on Xilinx FAGA Kit

Part Number: SN65DP159

Hi guys,


I have a Display port link trainging fail issue with TI SN65DP159.
I use "inrevium TB-FMCH-DP3" as RX of source device and want to light-on second monitor which is connect with FPGA board under normal mode.
Then display port will do link training automatically after tranfering display port initialing command, bout result is fail.
(Inrevium TB-FMCH-DP3 uses TI SN75SP130 for Source(TX) and SN65DP159 for Sink(RX).)
After changing source device (Apple Macbook + Type-C to DP cable ), the link trainging is successful and second monitor can be light-on.
So we think the root cause is TI SN65DP159 phy is not compatiable with almost video cards phy (Nivida and AMD), could anyone provide soulution?

Here is my H/W environment:
ZCU102 Evaluation Kit (as Sink) is connected to PC with Nvidia GTX1070 (as Source) through inrevium TB-FMCH-DP3 to light-on second monitor.

Thank you in advance.
