Is it possible to change (increase) the LVDS drive strength on the i.MX6 Quad LVDS output?
The Innolux display we are using have now changed their internal drive circuit and we can not get it working again after they changed it.
After measuring the LVDS signals they look fairly bad, so I suspect that the drive strength might be to low for this specific display panel circuits.
Hello,
Regarding LVDS output buffer impedance, the LVDS interface complies with TIA/EIA 644-A standard. See, TIA/EIA STANDARD 644-A, “Electrical Characteristics of Low Voltage Differential Signaling (LVDS) Interface Circuits” for details.
Best regards.
