Modern electronic products are becoming more compact and functions of electronic products are constantly updated and improved. As a result, traditional connectors are not enough to satisfy the needs of high-speed signals, new high-speed connectors are needed. Backplane connectors are mainly used to connect the backplane of system components, which can often be found in computers, communications and other systems. The 70238-101LF is a high-speed backplane connector is one of them, and this article will illustrate its application field and principle of work in details.

Application Field of 70238-101LF

The 70238-101LF backplane connector is a type of mid-density connector that is designed for high-speed signal in mid-level system density platforms. It commonly used for applications with a mid-skew and up to 10,000 mating cycles. Generally speaking, 70238-101LF backplane connection is suitable for many systems, including but not limited to enterprise networking, switches, servers, telecommunication and consumer electronics, etc. In addition, the connector also has a high signal integrity, which allows it to be applicable to many high-speed systems that require high performance, such as high-definition video, data storage, gaming systems, etc. In short, MULTIGIG RT and XT 70238-101LF backplane connector are applicable to many sophisticated systems.

Working Principle of 70238-101LF

The 70238-101LF backplane connection is specifically designed for high speed signal transmission so its wiring principle is complicated. According to what have been researched, the connector is designed with high speed differential signal lines which are connected to the high speed differential driver unit. The 70238-101LF backplane connector is based on an array of high speed differential lines called “Data Strobe” or “Strobe Lines”, which are connected to both the receiver circuit as well as the differential driver unit of the sender circuit. The Data Strobe line signal depends on different factors such as oscillator waveforms, oscillator frequency and transmitter impedance. For example, when the frequency is higher, the levels of the data strobe’s switching current become lower. The maximum transmission speed of DC to 85MHz is supported by the 70238-101LF backplane connection, which uses four differential pairs designed by PCIe Gen.2.

Utilizing the Data Strobe technology, the 70238-101LF backplane connection is able to sense automatically the speed requirements of the data transfer and adjust its clock automatically, which helps to improve the performance significantly. Moreover, the 70238-101LF backplane connector also features with low signal cross-talk and high speed signal integrity capability, which simultaneously guarantees the transmission rate reach up to 10 Gbps per differential signal pair.

Conclusion

To conclude, the 70238-101LF is a kind of high-speed backplane connector which is applicable to many high-level system platforms, such as enterprise networking, switches, servers, telecommunication and consumer electronics, etc. The connector is equipped with high speed differential signal lines, and is based on the Data Strobe technology as well as the 4 differential pairs PCIe Gen.2, which allows its clock to sense automatically and adjust to the speed requirements. In addition, this connector also offers low signal cross-talk and high signal integrity capabilities with its transmission rate reaching as high as 10 Gbps per differential signal pair. With all of these features, the 70238-101LF backplane connection offers reliable and high performance to its users.
