What is MIPI CSI-2 interface?

The CSI-2 MIPI interface is a digital core supplied with a multi-lane D-PHY that implements all protocol functions defined in the MIPI CSI-2 specification, providing an interface between the system and the MIPI CSI-2-compliant camera sensor.

How does MIPI CSI-2 work?

MIPI CSI-2 is a high-bandwidth interface between cameras and host processors. The finished packet is passed to the lane distribution system, which works with MIPI D-PHY and converts the CSI-2 packet into multiple D-PHY high-speed bursts which are sent across the physical link.

Is MIPI CSI bidirectional?

MIPI CSI-3 is a high-speed, bidirectional protocol primarily intended for image and video transmission between cameras and hosts within a multi-layered, peer-to-peer, UniPro-based M-PHY device network. It was originally released in 2012 and got re-released in version 1.1 in 2014.

What is MIPI sensor?

MIPI CSI-2 interface provides flexibility for next-generation embedded vision systems. Developed by the MIPI Alliance (www.mipi.org), MIPI CSI-2 defines an interface between an image sensor module and a host processor such as a System on Chip (SoC) and suits single or multi-sensor embedded vision applications.

Is MIPI double data rate?

When used with MIPI I3C v1. 0 Single Data Rate (SDR) mode, the interface delivers data at 12.5 Mbps. It delivers 25 Mbps when used with MIPI I3C v1. 0 High Data Rate (HDR) Double Data Rate (DDR) mode.

What is CSI and DSI?

These interfaces were designed for high bandwidth video input (CSI) and output (DSI). These state-of-the-art SoCs provide CSI-2 D-PHY interfaces which can have a transmission rate of 1.5 to 2.5 Gbps/lane. One such interface consists of a maximum of 4 data lanes and one clock lane.

Where is MIPI used?

MIPI DSI has been widely adopted. It is ubiquitous in smartphones and also being used in tablets, laptops and laptop/tablet hybrids. It is also being implemented by the automotive industry for dashboard displays and in-car infotainment systems, and used in wearables, IoT and virtual/augmented reality applications.

What is MIPI CSI DSI?

These interfaces were designed for high bandwidth video input (CSI) and output (DSI). These state-of-the-art SoCs provide CSI-2 D-PHY interfaces which can have a transmission rate of 1.5 to 2.5 Gbps/lane.

Is MIPI DDR?

What is C-PHY and D-PHY?

The D-PHY is a simple source synchronous PHY that uses one clock lane and a varying number of data lanes. The C-PHY uses encoded data to pack 16/7 ≈ 2.28 bits/symbol, while the D-PHY does not use any encoding.
