Introduction

The MIPI D-PHY (Directly Pluggable High-Speed Interface) is a high-speed interface standard used for connecting image sensors to System-on-Chip (SoC) devices. It is widely used in various applications, including mobile devices, automotive systems, and industrial equipment. In this article, we will discuss the MIPI D-PHY image sensor with SoC, its architecture, and its applications.

MIPI D-PHY Architecture

The MIPI D-PHY is a high-speed interface that uses a differential signaling scheme to transmit data between the image sensor and the SoC. It consists of two main components: the transmitter (TX) and the receiver (RX). The TX is responsible for converting the digital data from the image sensor into a differential signal, while the RX is responsible for receiving the differential signal and converting it back into digital data.

The MIPI D-PHY uses a 1.5 Gbps per lane data rate, which is achieved through the use of a 2:1 multiplexer and a 1:2 demultiplexer. The interface also supports a 3.0 Gbps per lane data rate, which is achieved through the use of a 4:1 multiplexer and a 1:4 demultiplexer.
