Series Termination for LVDS

[vigneshvasudeva]

Is it necessary to provide series termination resistor at LVDS data and clock lines of I.MX6?

If yes, what value is preferred?

Hi Vignesh

IMX6DQ6SDLHDG sect.3.10 LVDS recommendations

Use the following recommendations for the LVDS.

• Follow standard high-speed differential routing rules for signal integrity.

• Each differential pair should be length matched to ± 5 mils.

• LVDS differential pairs should have a differential impedance of 100 Ω.

If it is standard LVDS LCD it already has proper input termination.

Best regards
