Backplane connectors are among the most important components of a backplane system and are responsible for carrying high-speed signals between adjoining printed circuit cards. A specialized type of backplane connector is the 50004-5392E, which has become a widely used solution in higher-end systems. This article looks at the 50004-5392E, its application field and working principle.

Overview of the 50004-5392E

The 50004-5392E is designed to provide two pairs of unshielded, high-speed differential signal paths in the data plane. Each of these paths can be configured for either single-ended, differential signaling, or unipolar, voltage. The connector has a wide range of application needs from the ever-increasing performance requirements of Gb Ethernet to the higher-speed applications such as Infiniband. The connector comes in a standard 30mm x 50mm profile that is compatible with many of the industry-standard backplanes, making it suitable for a broad range of system needs.

Application Field for the 50004-5392E

The 50004-5392E is uniquely suited for interconnecting component parts of diverse systems. Its strong differential signal capacity makes it well-suited for transmitting data across multiple layers of address, telecommunications and electrical switching applications. For such applications, the connector is capable of operating between 3.3 to 5 volts, providing a much higher speed than conventional connectors.

Additionally, its compatibility with a variety of backplanes allows the connector to significantly reduce system complexity and cost. It is also highly suitable for use in Small Form-Factor Pluggable (SFP) connectors, allowing for increased cable density and reduced power consumption. Finally, the 50004-5392E is suitable for high-speed networking applications such as Ethernet and infiniband.

Working Principle

The 50004-5392E connector operates on the basis of dual differential signal path technology. This means that the connector carries two pairs of signal paths, each dedicated to singular, differential or unipolar signaling, depending on the needs of the system. The inner pair of signal paths acts as a high-speed differential link, carrying up to 10 Gb/s each. The outer pair of signal paths is configured as either single-ended or unipolar (for transmitting a single voltage across two lines).

Each of the four signal paths is then accompanied by four terminal pins, allowing for improved connection quality and reduced crosstalk. The four pins are placed in an array of 0.1mm, increasing signal stability and providing for better signal-to-noise ratio. Finally, the 50004-5392E has an integrated, embedded ferrite to further improve signal strength.

Conclusion

For high-end systems, the 50004-5392E is an excellent choice of backplane connector. With the ability to provide two pairs of unshielded, differential signal paths and the capability to run at up to 10Gb/s, the connector is a highly suitable choice for many networking and telecommunications applications. Additionally, its compatibility with a variety of backplanes makes it perfectly suited for high-density, low-cost and low-power systems.
