Maximum length of high-speed LVDS cable in automotive environment versus using SerDes
The standard deciding factor of whether a given transmission distance is practical, is how much jitter is observed by receiving nodes. This is application dependent; some applications require 5% or less jitter, whereas others tolerate up to 20%: https://www.analog.com/media/en/technical-documentation/application-notes/an-1177.pdf

There are a number of studies that look at how the signal integrity is affected by the transmission rate and cable length. However, normally you did not spec the maximum cable length for your application:
