imx6 hdmi cable length

[kurkinalexandr]

Hello.

I wonder if there is any restriction for hdmi cable length.

For example we have 1280x800 resolution 60fps, so what maximum length can have our hdmi cable to support this resolution correctly.

We have imx6 quad inside cm-fx6 module.

Thanks

Hi Fan

length is defined mainly by cable quality, so voltage at receiver end will be:

Input Differential Voltage Level >150mV (min.)

as stated in sect.4.2.5 HDMI Sink TMDS Characteristics HDMI specification.

May be useful to check AN4671 HDMI Compliance Test Specification
