About MIPI & interfacing specs

The powerful model C, a MIPI CSI-2 camera series, gives embedded system developers access to high performance image sensors popular in the machine vision industry. All our model C are equipped with a MIPI interface according to the standardization which allows you to connect to the available hardware at the market.

Data stream: MIPI CSI-2 D-PHY 1.0 with 8 lanes, 1 clock. The data stream is transmitted over two flat cables.

MIPI used in the products of purespectra Ltd.

The MIPI CSI-2 v1.0 specification was released in 2005. PureSpectra is using D-PHY standard (instead of C-PHY) as a physical layer option. The protocol is divided into the following layers:

Physical Layer (D-PHY)
Lane Merger Layer.
Low Level Protocol Layer.
Pixel to Byte Conversion Layer
Application Layer

About D-PHY

Versions 1.0 and 1.1 of UniPro use MIPI's D-PHY technology for the off-chip Physical Layer. This PHY allows inter-chip communication. Data rates of the D-PHY are variable, but are in the range of 500-1000 Mbit/s (lower speeds are supported, but at decreased power efficiency). The D-PHY was named after the Roman number for 500 ("D").

The D-PHY[3] uses differential signaling to convey PHY symbols over micro-stripline wiring. A second differential signal pair is used to transmit the associated clock signal from the source to the destination. The D-PHY technology thus uses a total of 2 clock wires per direction, plus 2 signal wires per lane and per direction. For example, a D-PHY might use 2 wires for the clock and 4 wires (2 lanes) for the data in the forward direction, but 2 wires for the clock and 6 wires (3 lanes) for the data in the reverse direction. Data traffic in the forward and reverse directions are totally independent at this level of the protocol stack.

The D-PHY also supports a Low-Power Data Transmission (LPDT) mode and various other low-power modes for use when no data needs to be sent.

About CSI

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]. The PureSpectra camera modules are producing an 8 bits signal which can be transmitted using the CSI-2 D-PHY 1.0 standard
