Arasan Chip Systems is a leading System on Chip (SoC) Intellectual Property (IP) provider of a complete suite of Mobile Industry Processor Interface (MIPI) compliant IP solutions, which consists of IP cores, verification IP, software stacks and drivers, protocol analyzers, hardware platforms(HVP’s) for software development and compliance testing and optional customization services.
The Mobile Connectivity (MIPI) compliant IP cores are interface building blocks that simplify interconnect architectures in mobile platforms. This leads to smaller footprint, greater inter-operability between mobile IP, chips and devices from diverse sources and lower power and Electro Magnetic Interface (EMI).
Arasan IP Core that functions as a MIPI Camera Serial Interface (CSI-2 Combo) Receiver, which interfaces between a peripheral device (Camera module) and a host processor (baseband, application engine). The CSI-2 Combo Receiver IP communicates over a D-PHY (or) C-PHY serial link to image processing block, part of the application engine. The Arasan CSI-2 combo IP is MIPI compliance and provides a standard, scalable, low-power, high-speed interface that supports a wide range of higher image resolutions.

Features
Compliant with the following MIPI specifications
CSI2 specification v2-1
DPHY specification v2-1
DPHY specification v1-2
CPHY specification v1-2
CSI-2 Combo Receiver Core features:
Use of either D-PHY/C-PHY by user configuration
Different Configuration allowed for multiple use cases,
4-Lane/8-Lane D-PHY / 3-Lane C-PHY
Lane Configurability depending on the bandwidth requirements of the application, up to 8-lanes for DPHY and up to 3-lanes for C-PHY
High Speed (HS) receiver rates of 182Mbps (80Msps) to 6840Mbps (3Gsps) per lane with C-PHY interface
High Speed (HS) receiver rates of 80Mbps to 1500Mbps per lane without calibration, 1500Mbps to 2500 Mbps with skew calibration and 2500Mbps to 4500Mbps with equalization in D-PHY interface
Supports for Alternate Low Power State (ALPS) in CPHY mode
Support for Ultra Low Power Mode (ULPS)
Single (or) Optional Multi-Pixel mode interface to ISP. The multi-pixel mode is used in high bandwidth requirement applications to lower the ISP clock frequency requirement.
Optional Pixel Level Interface to ISP with HSYNC, VSYNC, DATA and DATA VALID
Streams the received pixels onto eight data channels(customizable) based on the channel configurability from ISP
Separate data channel for the short generic packets
Support for all packet level errors, Protocol Decoding Level errors
Support for cut-though (or) store and forward mode. Cut-through mode makes use of shallow Memory for memory critical applications.
Optional support for Compressed data formats
Optional support for different error counting
Optional support for Data scrambling
Support for VC Extension feature as 16 virtual channels in DPHY mode and 32 virtual channels in CPHY mode
Pixel formats supported
RAW data type – RAW6,RAW7,RAW8, RAW10, RAW12, RAW14,RAW16, RAW20
YUV data type – YUV422-8bit, YUV422-10bit
RGB data type – RGB888, RGB666, RGB565, RGB555, RGB444
Host interface for register configuration and monitoring,
Used for programming both CSI-2 and PHY related registers. Reserved address space [0x00 – 0x0F] for the PHY related registers. Optional support for the AHB/APB Interface
