The Arasan MIPI CSI-2 Receiver IP Core functions as a MIPI Camera Serial Interface Receiver, between a peripheral device (Camera module) and a host processor (baseband, application engine). The Arasan MIPI CSI-2 Receiver IP provides a standard, scalable, low-power, high-speed interface that supports a wide range of higher image resolutions.
Arasan MIPI CSI-2 Receiver is compliant to MIPI CSI-2 v1.3 specification and supports DPHY v1.2 and the MIPI C-PHY v1.1.
Arasan offers the C-PHY in a combination configuration that supports both C-PHY interfaces and D-PHY interfaces. Our implementation makes efficient use of the high frequency signally pins for a minimal overhead to support both physical interfaces.

Features
Use of either D-PHY/C-PHY by user configuration
Different Configuration allowed for multiple use cases
4-Lanes/8-Lanes D-PHY / 3-Lanes C-PHY
Lane is configurable 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 to 5714Mbps per lane with C-PHY interface
High Speed (HS) receiver rates of 40Mbps to 2500Mbps per lane with D-PHY interface
Supports 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 configuration 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 FIFO. Cut-through mode makes use of shallow Memory for memory critical applications.
Optional support for Compressed data formats
Optional support for different error counting
Pixel formats supported
RAW data type – RAW8, RAW10, RAW12, RAW14
YUV data type – YUV422-8bit, YUV422-10bit
RGB data type – RGB888, RGB666, RGB565, RGB555, RGB444
All user Defined data types / JPEG
Generic 8-bit long packet data types
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
