The Camera Serial Interface (CSI) is a specification of the Mobile Industry Processor Interface (MIPI) Alliance. It defines an interface between a camera and a host processor. The latest active interface specifications are CSI-2 v3.0, CSI-3 v1.1 and CCS v1.0 which were released in 2019, 2014 and 2017 respectively.[1][2][3]
Standards[edit]
Baseband, application engine. The table below illustrates optimal MIPI CSI and PHY con˝ gurations for popular 4K imaging format: TECHNOLOGY BRIEF Evolving CSI-2 Speci˜ cation CSI-2 over D-PHY and C-PHY D-PHY as used in CSI-2 is a unidirectional di˜ erential interface with one 2-wire forwarded clock lane and one or more 2-wire data lanes. The voltage level test determines whether the MIPI CSI-2 receiver D-PHY has correctly terminated the MIPI CSI-2 output from the. ADV7280-M, ADV7281-M, ADV7281-MA, or ADV7282-M transmitter device. Program the transmitter device into free run mode to output a test pattern over the MIPI CSI -2 link.
CSI-1[edit]
CSI-1 was the original standard MIPI interface for cameras. It emerged as an architecture to define the interface between a camera and a host processor. Its successors were MIPI CSI-2 and MIPI CSI-3, two standards that are still evolving.
CSI-2[edit]
The MIPI CSI-2 v1.0 specification was released in 2005. It uses either D-PHY or C-PHY (Both standards are set by the MIPI Alliance) as a physical layer option. The protocol is divided into the following layers:
In April 2017, the CSI-2 v2.0 specification was released. CSI-2 v2.0 brought support for RAW-16 and RAW-20 color depth, increase virtual channels from 4 to 32, Latency Reduction and Transport Efficiency (LRTE), Differential Pulse-Code Modulation (DPCM) compression and scrambling to reduce Power Spectral Density.[4]
In September 2019, the CSI-2 v3.0 specification was released. Skin pack windows 8.1. CSI-2 v3.0 introduced Unified Serial Link (USL), Smart Region of Interest (SROI), End-of-Transmission Short Packet (EoTp) and support for RAW-24 color depth.[5][6]
CSI-3[edit]Mipi Dsi Specification Pdf
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.[7] Frontpage 2003 on windows 10.
Camera Command Set (CCS)[edit]
The Camera Command Set (CCS) v1.0 specification was released on November 30, 2017. CCS defines a standard set of functionalities for controlling image sensors using CSI-2.[8][9]

Technology & Speeds[edit]
For EMI reasons the system designer can select between two different clock rates (a and b) in each of the M-PHY speed levels.[10]
