Mipi Csi 2 Specification Pdf
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]

Understanding and Performing MIPI® D-PHY Physical Layer, CSI and DSI Protocol Layer Testing Application Note Introduction Currently many technologies are used in designing mobile or portable devices. These current interfaces are not well defined and are proprietary for each component or subsystem vendor.
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. MIPI CSI-2 RX Controller The MIPI CSI-2 RX Controller core consists of multiple layers defined in the MIPI CSI-2 RX 1.1 specification, such as the lane management layer, low level protocol and byte to pixel conversion. The MIPI CSI-2 RX Controller core receives 8-bit data per lane, with support for up to 4. CONFIDENTIALCONFIDENTIAL © 2015 MIPI Alliance, Inc. All rights reserved. Wireless wifi driver for hp laptop.

Standards[edit]
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:
- Physical Layer (C-PHY/D-PHY)
- Lane Merger Layer.
- Low Level Protocol Layer.
- Pixel to Byte Conversion Layer
- Application Layer
Mipi Csi-2 Spec Pdf
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. 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 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]
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]
| M-PHY speed | Clock rate | Bit rate |
|---|---|---|
| Gear 1 | G1a | 1.25 Gbit/s |
| G1b | 1.49 Gbit/s | |
| Gear 2 | G2a | 2.5 Gbit/s |
| G2b | 2.9 Gbit/s | |
| Gear 3 | G3a | 5 Gbit/s |
| G3b | 5.8 Gbit/s |
