MIPI is rapidly spreading and expanding in markets other than mobile applications. MIPI, which has been meeting the high-resolution requirements of cameras mounted on smartphones, has a wide variety of high-resolution compatible sensors. MIPI has been increasingly considered for embedded game bet88 systems other than mobile applications in recent years due to the growing demand for higher resolution.
In this article, we are taking a deep dive into MIPI to understand its specifications and characteristics.

Bắt đầu dưới dạng tiêu chuẩn dành riêng cho thiết bị di động
MIPI đạt được tốc độ truyền dữ liệu cao bằng cách sử dụng công nghệ truyền tải điện áp thấp như LVDS thực tế, có nhiều tiêu chuẩn lớp vật lý cho MIPI.
game bet88 first physical (PHY) layer standard established in 2008 was D-PHY v1.0, with a maximum data transmission rate of 1 Gbps per lane (Table 1). D-PHY v1.0 is a standard optimized for mobile devices for target applications, with two optimization points: simplicity and low power consumption.
game bet88 first, simplicity, was achieved by adopting a separated clock transmission method in which data and clock signals are transmitted on separate signal lines. game bet88 separated clock transmission method has game bet88 challenge that as game bet88 transmission distance increases, game bet88 timing at which game bet88 data and clock signals arrive at game bet88 receiver IC becomes misaligned due to skew caused by differences in signal line lengths and characteristics. In game bet88 worst cases, transmission errors may occur. However, for signal transmission inside mobile devices, sending signals over such long distances is unnecessary. In practice, game bet88 distance transmitted with D-PHY v1.0 is in game bet88 tens of centimeters. It can be said that this standard was developed with game bet88 decision to adopt game bet88 separated clock transmission method, prioritizing simplicity over transmission distance.

Ứng dụng ô tô mới nổi cho các tiêu chuẩn lớp vật lý
Như đã đề cập trước đó, tiêu chuẩn MIPI có nhiều tiêu chuẩn lớp vật lý. Bộ khuếch đại tín hiệu truyền và phương pháp truyền đồng hồ được phân tách là D-phy v1.0, nhưng bằng cách thêm các công nghệ khử chiếu và cân bằng, tốc độ truyền tải dữ liệu tối đa đã được tăng lên 6 Gbps mỗi làn.

M-PHY is a physical layer standard for Inter-Processor Communication (IPC) in mobile devices. By applying equalizer technology and 8B10B modulation technology, game bet88 maximum data transmission rate has been increased to 6 Gbps per lane, similar to C-PHY.
D-PHY v3.0, C-PHY, and M-PHY are all aimed at mobile devices, which are game bet88 target applications for game bet88 MIPI standard. game bet88 standard can be said to have been upgraded time and time again to support new uses within game bet88 scope of mobile devices by adopting new transmission technologies and increasing its maximum data transmission speeds.
However, in September 2020, a standard was established that deviates significantly from this trend. That is in reference to A-PHY, a physical layer standard for automotive applications. This is intended for data transmission applications between cameras and displays inside automobiles. While this is a category of "high-speed data transmission standards within devices," game bet88 scope of "mobile devices" has gone far beyond this category.

Giải quyết vấn đề với v-by-one HS
Do đó, tiêu chuẩn lớp vật lý MIPI đã phát triển đáng kể từ D-Phy V1.0 ban đầu.
The maximum data transmission rate of D-PHY is 1.0 Gbps for v1.0 and 1.5 Gbps for v1.1, which would be a high enough data transmission rate for general use. However, more than a transmission distance of several tens of centimeters is required for some applications. For example, a game bet88 module with MIPI D-PHY output (MIPI game bet88) is used to build an industrial IoT system. For crop monitoring in an orchard, the game bet88 module would be mounted on a fruit tree trellis and connected to a SoC board on the ground with a cable. Currently, with its D-PHY physical layer standard, MIPI needs more transmission distance.
One way to solve this transmission distance challenge is to use V-by-One HS, a high-speed interface technology. Here's how to use V-by-One HS: First, a transmitter IC connected to the game bet88 module converts MIPI signals compatible with D-PHY to V-by-One HS signals. This signal is then sent over an Ethernet cable or similar medium, and a receiver IC connected to a remote SoC board converts the V-by-One HS signal back to a MIPI signal (Fig. 1).
