About the failure of AD9361 using LVDS mode

XC7A200T+9361 has been used to verify the COMS mode and LVDS mode of 9361, both of which are correct。

 

But now with XC7Z100+9361, COMS mode is correct and LVDS mode is not available.The 9361 clock in LVDS mode is correct, but RX_0_N,RX_0_P all the way to RX_5_N,RX_5_P has no output.

 

The same problem exists with the XC7Z035+9361 approach

 

Both the schematic diagram and the PCB are correct because it works perfectly in COMS mode,

 

I tried to replace the 1.8v of 9361 with 2.5v, but it didn't work

 

Is it because ZYNQ's FPGA doesn't support the 9361 LVDS model?
