Backplane connectors play a critical role in high-speed, high-frequency, and high-density connectivity of most computer systems and networks. Specialized backplane connectors, such as the 50645-1150EBLF, provide superior signal and power integrity in a variety of applications. This article will discuss the application field and working principle of the 50645-1150EBLF.

The 50645-1150EBLF is an ultra-low profile high speed differential pair connector specifically designed for InfiniBand and Ethernet applications on high-performance backplanes. It has a unique board stack height of 3.98 mm, providing space savings of more than 64 percent compared to standard connectors. Its stack height is less than half the stack height of commonly used backplane connectors, allowing the cabinet to be more spacious and efficient.

The 50645-1150EBLF features two sets of differential signal pins that are potted on the board to maintain signal integrity. Every differential signal pair is expected to provide a robust S-parameter performance of greater than 21 dB up to 5.0 GHz. This ensures superior signal integrity for high speed data transmission and protection in harsh environments. In addition, this connector is equipped with an integral latching mechanism for secure mating.

The 50645-1150EBLF is ideally suited for Ethernet applications in harsh industrial environments. It is able to operate from -55 to +150 degrees Celsius, making it a reliable solution for use in industrial automation, communication systems and military applications. It also supports a variety of connector mounting methods such as direct soldering and press-fit for various applications. With its superior signal integrity and latching mechanism, the 50645-1150EBLF is an excellent choice for mission-critical applications.

The working principle of the 50645-1150EBLF is based on the concept of differential pairs. The connection consists of two parallel signal conductors of equal length and spacing. The impedance of the differential pair is determined by the characteristic impedance of the conductors, the distance between them and the shape of the wire. This principle further improves signal integrity compared to single line transmission due to its increased sensitivity to noise.

The connection of the differential pairs can be realized by two different techniques: via solder pins or board-to-board contacts. The combination of impedance matching and balanced transmission effectively reduces the influence of external noise and crosstalk and ensures high quality data transmission.

The 50645-1150EBLF is an economical and reliable high performance specialized backplane connector suitable for a wide range of applications. It offers superior signal integrity and noise immunity, enabling it to operate reliably in harsh environments. With its low profile and latching mechanism, it is an ideal choice for mission critical applications.
