Occasional ContributorWhy the lvds wave of true lvds tx channel is worse than the lvds wave of Emulated lvds tx when use true and Emulated lvds tx at the same time?
Hi everyone, I accounted one problem when I use true and emulated lvds tx at the same time. For Arria V GX FPGA, I use the same lvds_tx ip for Emulated and True lvds tx which serial factor is 2, ...
The problem is that Emulated and True tx should use the same I/O standard ----- LVDS_E_3R.

Occasional ContributorHi RSree,
The above solution is wrong, because I don't insert terminating resistor when I monitor the lvds wave on the true lvds I/O, so it's okay to use lvds standard for the true lvds I/O interface.
