Global data consumption has been growing rapidly. With the development and expansion of the traditional Internet and the Internet of Things Connector The demand for is also growing, and new and flexible backplane solutions are needed to meet the speed requirements. In this article, Xinpengbo connector manufacturers mainly share 2 kinds of backplane solutions commonly used by high-speed data transmission connectors!
Not all backplanes are the same. They provide different functions. When creating networks, data centers, storage and other equipment systems, it is necessary to understand key characteristics, such as the required density, data rate, slot spacing and bandwidth.
The most common design is the traditional backplane, which uses a right angle daughter card (RA DC) connected to the vertical backplane connector. Although designers are familiar with this architecture, compared with newer alternatives, it requires longer wiring channels and thicker substrates to meet signal density requirements and wiring capabilities. These problems limit the ability of traditional backplane connectors to adapt to higher data speeds, so designers are using a variety of innovative solutions to solve this problem.
Two common backplane solutions for high-speed data transmission connectors are as follows:
1. Four route backplane is a solution. Some four route backplane connector solutions provide more column to column space than traditional designs. They enable users to route four traces between vias by using a 3mm column to column spacing and a more dense 1.9mm spacing, which reduces the number of signal layers required for wiring connectors.
The four wiring backplane solution with a spacing of 3 mm provides lower crosstalk, which can take up space to produce strong signal integrity performance, but the increased spacing will produce greater spacing between chips, which means that fewer chips can be installed on a given card edge, thus reducing the linear density of connectors.
2. The other option is the coplanar backplane (right angle male with right angle daughter card), which can support various I/O protocols, so that pluggable modules can be used. The coplanar backplane is essentially a bridge card, which provides universal interconnection for various connector blades or line cards inserted into the backplane.
For example, some users may need to insert the RJ45 connector blade into the backplane, but other users (such as high-end data centers) may need faster data rates and zQSFP type I/O. On the coplanar backplane, users can connect Ethernet RJ45 connector The connection of is changed to SFP connection without unplugging any plug from the backplane, which allows system designers to use the existing backplane architecture while expanding to various I/O protocols.
The above two common backplane solutions for high-speed data transmission connectors are shared here.
