: The extended 4-meter reach is ideal for devices where the camera sensor and processor are physically separated.
The v2.5 update focused on extending reach and reducing implementation complexity: Alternate Low Power (ALP) Mode mipi d-phy specification v2.5 pdf
The specification maintains backward compatibility with previous D-PHY versions. A v2.5 compliant IP block can generally auto-negotiate or be configured to operate at older data rates (e.g., v1.2 speeds) to interface with legacy processors or sensors. : The extended 4-meter reach is ideal for
