| Feature | D-PHY | M-PHY | | :--- | :--- | :--- | | | Cameras (CSI-2), Displays (DSI) | Storage (UFS), Inter-chip (LLI) | | Signaling | High-Speed Differential + Low-Power Single-Ended | High-Speed Differential + PWM | | Max Speed | Generally lower (though D-PHY v3.5 is improving) | Much higher (Geared toward 10G+) | | Complexity | Lower complexity, lower cost | Higher complexity, higher efficiency |
: Optimized for low power consumption using "burst-mode" and multiple power-saving states.
Features multiple power-saving modes (like HIBERN8 ) that trade off power consumption against recovery time.
PWM Mode is unique to M-PHY and is designed for lower-speed control signaling and low-power data transfer.
One of the defining characteristics of the M-PHY specification is its support for two distinct signaling modes. This dual-mode architecture allows designers to optimize the interface for either maximum performance or maximum power conservation.
The primary goal of the M-PHY specification is to provide a scalable solution that minimizes pin count and power consumption while maximizing data throughput.
At speeds exceeding 5 Gbps, signal integrity is a major challenge. The specification details requirements for:
