MIPI Alliance’s M-PHY specification v3.0 provides a solid specification targeted to a variety of applications in the mobile electronics space. I hear some concerns about that this technology is new and engineers prefer to wait for the adoption to pick up before they use it.

Well, it is true that MPHY v3.0 specification is about 1 year old, however note that the M-PHY v1.0 specification was introduced about 3 years ago and was first adopted in DigRFv4 applications. There are several IC’s using M-PHY in production, here’s an example of a Fujitsu Baseband processor. The foundation of the circuitry for higher gears and features introduced in MPHY v3.0 were already established and used several years ago. Furthermore, MPHY v3.0 spec is used by several protocols including those defined by the MIPI alliance work groups (such as UniPro, CSI-3, LLI, DSI-2) and those adopted by other standard bodies which selected the MIPI M-PHY as the physical layer for these applications.
