This article introduces the relevant knowledge of "what is the difference between LVDS and MIPI interfaces". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The difference between the two interfaces can be seen more intuitively from the content of the transmission. The specific content of the transmission is as follows:

1. LVDS interface

On the table, slot0 to slot6 represent clock cycles, CHx_DATA0 to CHx_DATA3 represent 1 to 4 groups of data differential pairs, and video frames such as G0 are data.

2. MIPI DSI interface

Data is transmitted in the channel in the form of short packets (SP) or long packets (LgP) as needed. Refer to the relevant materials for the specific package format. Here we can see that the physical media of the LVDS interface and the MIPI DSI interface are the same differential line pairs, but the content of the transmission is really completely different.

The schematic diagram of 4-channel data channel allocation is as follows:

The data sequence can be divided into two modes: simultaneous termination and non-simultaneous termination (the following figure takes dual channels as an example):
