Introduction

The MIPI DPHY (Display PHY) architecture is a high-speed digital interface technology designed specifically for mobile and portable devices. It provides a reliable, low-power, and cost-effective way to transfer high-quality video and imaging data between a mobile device’s processor and its display or camera. In this white paper, we will explore the value proposition of the MIPI DPHY architecture and its advantages over other display interface technologies.

Value Proposition of MIPI DPHY

The MIPI DPHY architecture is built on a foundation of performance, power efficiency, and flexibility. It has been designed to meet the specific needs of mobile devices, where power consumption and size are critical factors. The value proposition of MIPI DPHY can be summarized in the following points:

• High Performance: MIPI DPHY can support a data transfer rate of up to 4 Gbps per lane, making it capable of transmitting high-quality video and imaging data without compromising on performance.
• Low Power Consumption: MIPI DPHY uses a low-voltage differential signaling (LVDS) mechanism, which requires less power than other interface technologies. Additionally, it supports power-saving modes such as HS-LP and LPDT, which further reduce power consumption.
• Flexibility: MIPI DPHY can support different data lane configurations, from 1 to 4 lanes, depending on the requirements of the device. It also provides the flexibility to choose the data rate and clock speed, allowing for customization to meet specific device needs.
• Cost-Effective: MIPI DPHY is a low-cost solution that helps to reduce the overall cost of mobile devices, making it an attractive option for manufacturers.

MIPI DPHY Architecture

The MIPI DPHY architecture consists of a transmitter and a receiver, each with their own specific functions. The transmitter is responsible for encoding the video or imaging data, while the receiver decodes the data and passes it on to the display or camera.

The transmitter block consists of four main blocks: the serializer, the lane mapper, the channel encoder, and the output driver. The serializer converts the parallel video data into serial data, which is then mapped onto the appropriate lane by the lane mapper. The channel encoder adds error correction coding and scrambles the data to ensure reliable transmission. Finally, the output driver amplifies and sends the encoded data to the receiver.

The receiver block consists of four main blocks: the input receiver, the channel decoder, the lane demapper, and the deserializer. The input receiver receives the encoded data and amplifies it for further processing. The channel decoder removes the error correction coding and descrambles the data. The lane demapper separates the data onto the appropriate lane, and the deserializer converts the serial data back into parallel data for display or imaging.
