Hello ,

From the above your reply when you said LVDS_E_3R working then I understood that channel is not differential end pair...I was trying to find part number and pin mapping sheet whether particular channel support dedicated LVDS channel

and you confirmed it is not ..Good

First thing i would give some input about what is LVDS_E_3R..as you said you are at beginning .it is good to learn when you see things " LVDS assignment for non dedicated differential pins as LVDS_E_3R .This standard required 3 external resistors.

I can comment with cyclone IV E LVDS can support around 800 MBPS with provide clock speed.I am not sure about particular board. But i did see few folks mentioned in forum that they tried out and successfully.

Below link is for references

In the method 2, can you help me to understand how to differentiate the channel ?

Thank you ,
