Backplane Connectors - Specialized

MP2-PS090-51S1-LR Application Field and Working Principle

Backplanes are essential components of many electronic systems, providing basic communication between subsystems. As they are typically selected based on application, the design of the backplane must be well matched to the specific technical requirements of the system. Among the many types of backplane connectors, the MP2-PS090-51S1-LR is a specialized type with unique features and characteristics to handle specific applications. This article provides an overview of the application field and general working principle of this connector type.The MP2-PS090-51S1-LR backplane connector is typically used in wireless systems that require both high datarates and long range communications. It is optimized for use in point-to-point and network-based communication systems, such as 802.11a/b/g/n, 2.4GHz/5GHz mesh networks, antenna-less Wi-Fi and Bluetooth networks, wireless data transfer, and other similar applications. It is specially designed to reduce EMI and crosstalk in these systems.The special feature of the MP2-PS090-51S1-LR backplane connector that makes it suitable for these applications is its ability to carry high currents with a relatively small form factor. The connector features 4 rows of 10 pads, which are divided into 5 differential pairs. These pairs are further split into two lanes, each of which carries a different pair of signals. This allows for high data rates and low crosstalk, as well as fast communication between_modules that use different protocols.The general working principle of the MP2-PS090-51S1-LR backplane connector is similar to that of other backplane connectors. It connects the backplane with other modules and performs signal continuity between them. In this case, the signal is passed through the differential pairs, and each lane is equipped with its own ground plane. This helps to reduce crosstalk between the lanes, as well as providing EMC immunity. Additionally, the connector also provides integrated ESD protection for the pins, and an impedance-controlled signal line.As mentioned, the MP2-PS090-51S1-LR backplane connector has been specially designed for use in wireless systems. It is capable of carrying high currents and can handle data rates up to 8Gbps, while also providing low crosstalk and EMC immunity. In addition, the integrated ESD protection and impedance-controlled signal line help to further reduce EMI and protect the connectors from damage. All this makes the MP2-PS090-51S1-LR a reliable and robust choice for applications requiring fast and reliable inter-module communication between different protocols.
