Backplane connectors are a special type of electrical connectors used in a variety of electronic applications. They are used to provide power and ground connections between device boards. The 76011-3123 backplane connector is an example of a specialized backplane connector specifically designed to be used in SAS (SCSI-3) applications. In this article we will discuss the application field and working principle of the 76011-3123 backplane connector.

Introduction To 76011-3123 Connector

The 76011-3123 backplane connector is a dual differential Multi-Drop (MDP) SCSI-3 backplane connector designed to meet SAS and SATA specifications. It features 75 ohm impedance, and is typically used in server or storage applications. The connector is designed with a tried-and-true SAS architecture, which includes four, wide-body SFF-8482 (small form factor) connectors and two narrow-body SCA-2 connectors.

Application Field

The 76011-3123 connector is suitable for SAS (SCSI-3) applications in many applications. It is widely used in server and storage applications. This includes server and storage applications such as Storage Area Network (SAN), Network Attached Storage (NAS), RAID and Tape Libraries. The connector is also used in video streaming applications and other applications which are sensitive to data transfer delays.

Working Principle

The working principle of the 76011-3123 connector is similar to the working principle of other backplane connectors. The four wide-body SFF-8482 connectors act as transmitters and receivers and the two narrow-body SCA-2 connectors acts as reflectors. Each port has twelve serialized differential pairs and a ground line, which is used to provide power and ground connections. The data signals are both transmitted and received on the same port simultaneously, using the different pairs of differential signals. The differential signals enable maximum signal integrity and the reflector port helps to reduce the amount of noise.

The 76011-3123 backplane connector also supports hot plugging; i.e., you can plug and unplug the ports without having to power down the equipment. This is beneficial in scenarios where upgrades or repairs need to be done quickly. The connector also supports different speeds of data transfer, such as 1.5 Gbps and 3 Gbps. Finally, it has a uni-directional termination, meaning the transmit and receive pairs of wires cannot be mixed up as the connector is designed such that the pins at the opposite end of the connector are symmetrical.

Advantages Of 76011-3123 Connector

The 76011-3123 connector offers several advantages when compared to other backplane connectors. First, it supports hot plugging, which allows users to plug and unplug ports quickly without having to power down the equipment. Second, it is designed to provide maximum signal integrity, which is important in applications such as video streaming. Third, it supports different speeds of data transfer, meaning users can select the most appropriate speed for their application. Fourth, it features a one-directional termination, which prevents errors in plugging the connector. Finally, it has been designed to withstand high speeds of vibration and shock, making it a perfect choice for applications where the highest levels of vibration and shock may be encountered.

Conclusion

The 76011-3123 backplane connector is a specialized connector designed to meet SAS and SATA specifications. It is suitable for SAS (SCSI-3) applications, and is widely used in server and storage applications such as Storage Area Network (SAN), Network Attached Storage (NAS), RAID and Tape Libraries. The working principle of the 76011-3123 connector is similar to other backplane connectors, with the added advantage of being able to provide maximum signal integrity and support different speeds of data transfer. It also features a uni-directional termination, which prevents errors when plugging the connector. This makes the 76011-3123 backplane connector an ideal choice for server and storage applications where high speeds of vibration and shock may be encountered.
