MIPI D-PHY1.2 CSI/DSI TX and RX

Overview

The MIPI D-PHY + DSI/CSI Controller IP is a versatile solution designed for high-speed data transmission in mobile and multimedia applications. It supports MIPI D-PHY 2.0 standards. The IP features a compact design with built-in I/O and ESD protection, optimized for robust performance and low power consumption. It enables seamless connectivity with D-PHY based sensors, making it ideal for SoCs in consumer electronics, automotive, and IoT devices.

The D-PHY supports high-speed and low-speed modes for bidirectional data transfer. It offers both receiver and transceiver solutions, ensuring efficient data transmission in D-PHY mode.

The DSI Controller implements the MIPI DSI-2 protocol, enabling high-speed display communication. It packs and distributes pixel data to the D-PHY, supporting features like pixel/byte packing, low-level protocol, and lane management. The DSI TX transmits data to the display, while the DSI RX reconstructs data streams from the display, ensuring error-free communication. This IP is ideal for mobile devices, AR/VR headsets, and automotive displays, offering high performance and low latency.

The CSI Controller implements the MIPI CSI-2 protocol, facilitating camera-to-processor communication. It packs pixel data for transmission via the D-PHY and reconstructs data streams at the receiver end. The CSI TX/RX supports error detection (ECC/CRC) and lane management, ensuring reliable data transfer. This IP is widely used in smartphones, drones, surveillance cameras, and automotive ADAS systems, providing high-speed, low-power connectivity for image sensors.
