Introduction

Backplane connectors are special purpose components used for relaying signals between two or more printed circuit boards. They offer high-speed interfaces and are designed to ensure reliable data transfer and low-power consumption. 0746 511002 is a type of backplane connector of very high density and is suitable for very high speed applications. This article serves to discuss its application field and working principle.

Application Field of 0746 511002 Backplane Connector

0746 511002 is a high-speed connector with 10 single row of pins, which is four times denser than the existing hierarchical backplane connectors. It is used for applications requiring high density and speed. It is small in size but capable of very-high data rates. These include Ethernet, Fibre Channel, InfiniBand, Voice over IP and other high data rate applications.0746 511002 can also be used in line cards and backplanes used for telecom and industrial applications. It can support symmetric transfer rates of up to 10.3 Gbps and up to 435 pins. It is ideal for applications which require high signal bandwidths and which are capable of very-low crosstalk performance.

Working Principle of 0746 511002 Backplane Connector

The 0746 511002 backplane connector employs a unique signal routing technique called hierarchical routing. The high-speed signals are routed from the connector through multiple layers of the printed circuit boards. Every layer is connected by multiple traces leading to the main contact points. This technique ensures that the high-speed signals are not compromised by other noise or signals on the board and hence ensures better performance.The 0746 511002 also includes signal integrity features such as impedance control, equalization, and line termination. This helps achieve reliable operation even at very high speeds, and enables it to support different signal protocols and rates. Furthermore, the connector is designed to minimize any possible crosstalk between signals.The 0746 511002 also comes with a mechanical interface that provides mechanical and electrical compatibility between the backplane and line cards. This ensures that both the line card and the backplane can be integrated into the same system without any compatibility issues.

Conclusion

The 0746 511002 is a high-density, high-speed backplane connector designed for applications requiring high signal bandwidths and very-low crosstalk performance. It employs unique hierarchical routing techniques to ensure reliable data transfer while minimizing crosstalk. Furthermore, it also offers a mechanical interface for compatibility between line cards and the backplane.
