I got several inquiries about adoption rate of physical layers across the mobile and adjacent industries after posting the video showing D-PHY v1.2 silicon on 16nm I realize that it’s debatable if it’s fair to compare one spec vs the other. However, I would like to note that de-facto standard has a lot of weight and it is what sets it apart compared to other potential specifications which only a few vendors select. Once a certain standard is well adopted across the industry, it establishes an entrenched position and cannot be replaced instantly. Any potential replacement standard need to take into consideration backwards compatibility to ensure vendor’s investment in the de-facto standard continues to bear fruits. It requires a phased approach towards replacing a successful standard and it’ll only be possible if the replacement standard has proven benefits compared to the de-facto standard and that the transition period is not long and not painful.
