Types of MIPI Interface Standard
MIPI is a set of specifications for the pattern of mobile devices. It defines the protocol’s physical layer standards for interconnecting internal mobile device components. It has three unique physical(PHY) standards:
- MIPI D-PHY,
- MIPI M-PHY,
- And MIPI C-PHY.
What is MIPI D-PHY: MIPI D-PHY is a physical layer standard for connecting displays and cameras to baseband processors of mobile and portable devices. D-PHY is a synchronous link that works in either forwarded clocks or embedded modes.
Uses of MIPI D-PHY: MIPI D-PHY has many applications such as:
- Smartphones
- Tablets
- Drones
- Surveillance cameras
- Robots
- In-car infotainment and dashboard displays
- Automotive camera and radar sensors
Features of MIPI D-PHY: The following are the key features of MIPI D-PHY:
Scalability: D-PHY is scalable in single or multiple data lanes.
Flexibility: It is switchable between real-time high-speed differential mode and low-power single-ended mode.
Point-to-point Connectivity: D-PHY can connect between a host and device like a master and slave.
Forwarded Clock: This interface has a dedicated clock lane for the clock-forwarded synchronous link.
MIPI Protocols Supportability: D-PHY is a popular layer standard for the Display Serial Interface(DSI) and Camera Serial Interface(CSI-2).
What is MIPI M-PHY?
The M-PHY physical(PHY) layer interface is used for serial communication in mobile systems. It is designed for fast communication channels and flash memory-based storage systems.
