TMDS141 Diff pair swapping

Ray H.

Other Parts Discussed in Thread: TMDS141

The data sheet doesn't explicitly say so I'm asking here. Do all 4 of the TMDS pairs on the TMDS141 have the same characteristics, i.e. there is nothing special about the clock pair RXC/TXC compared to the data pairs RXn/TXn? I would like to swap the pairs around to aid routing to a HDMI connector.

Thanks,

Hi Ray,

You can swap these lanes, they just differ in Peak-to-Peak output jitter, this difference is very small it should not affect.
There are other devices where you can't do device because of clock detection features.

I did see the different jitter spec in the datasheet which is what made me question the swappability.

Thanks,
