MIPI CSI-2 Receiver

The Cadence® Receiver (RX) IP for MIPI® CSI-2SM is a fully-verified, configurable, digital core that is compliant with the MIPI Alliance CSI-2 v1.3 specification. The Controller IP is responsible for handling and decoding CSI-2 protocol-based camera or other sensor data stream and managing the forwarding or unpacking of payload data to the pixel-stream interfaces. It is an ideal solution to provide a high-speed serial interface between an application or image processor and MIPI CSI-2 compliant camera sensor.

Benefits

  • Full featured and highly configurable IP core that is area optimized for each application

  • Complete solution with complementary master/slave IP

  • Fully verified on an FPGA

  • Automotive variant with Safety Manual

MIPI CSI-2 Receiver Block Diagram

The RX Controller IP for CSI-2 allows the selection of multiple independent streams to support the control of the destination for each data packet (for example, Bayer input of ISP, RGB/YUV input of ISP, or DMA to memory).

The RX Controller IP for CSI-2 consists of a lane management module that connects via the PHY-Protocol Interface (PPI) to a D-PHY receiver module, an external register interface for configuration of the receiver IP, a CSI-2 protocol module for protocol decode, and a CSI-2 stream module for providing received CSI-2 packets from the D-PHY and providing synchronization information and pixels/packed data to the pixel stream interface. Each stream has an external memory interface that can act as a line buffer or as a short buffer to minimize latency.

Features

  • Compliant with MIPI CSI-2 v1.3 Specification

  • Support of the MIPI CSI-2 protocol over 1, 2, or 4 D-PHYSM data lanes

  • Support for D-PHY v1.2 Specification, up to 2.5G per lane

  • 32-bit Arm® AMBA® APB Slave programming interface

  • Continuous and non-continuous (gated) D-PHY byte clock support

  • Extended functions for Virtual Channel Extension (VCX) and RAW16/20 modes as defined for MIPI CSI-2 V2.0 Specification

  • Highly configurable independent stream interfaces

  • Programmable synchronization and interrupt (error and information) events
