The origin of HSD connector
HSD connection system (High Speed Data) is a high-performance data connection system, which is a fully shielded interconnection system. To prevent crosstalk and interference from external sources, the characteristic impedance is 100Ω. It was first launched by Rosenberger in 2007, leading the new trend of vehicle digital signal transmission at that time.
HSD provides two pairs of differential signal pairs for the development interface of the automotive industry, so it can not only send data according to low-voltage differential signaling (LVDS), it is widely used in automotive infotainment modules, cameras, head-up displays, etc., and can also be used for USB 2.0 / 3.0, Ethernet (10Base-T1s, 100BASE-TX, 100BASE-T1, 1000BASE-T1, BroadR-Reach) specifications, with high shielding efficiency.
Introduction to Signal Integrity of HSD Connectors and Harnesses
HSD is mainly a 4C shielded wire structure. In order to meet the high-speed signal transmission on the car, the high-frequency data requirements of the finished product must be guaranteed. Therefore, this type of bare wire needs to test the high frequency of the corresponding wire, and ordinary USB cables cannot be used.
HSD Connector Market Status
HSD connectors are usually used with Fakra, Mini-Fakra. In the application of the surround view ADAS system, the camera is connected to the wire harness through the Fakra connector, and the other end of the wire harness is connected to the HFM (Mini-Fakra) connector, so that the collected data can be transmitted to the vehicle surround view system (AVM), and then the HSD connector Connect the wiring harness, send the data to the host computer, and finally send the data to the display screen through the HSD+2 connector. HSD can not only send data according to low-voltage differential signal (LVDS), but also can be used in USD 2.0/3.0 and Ethernet specifications, with high shielding efficiency. With the introduction of automotive Ethernet, HSD connector will become a compatible solution.
Classification
HSD has a variety of integration types - single cavity/double cavity, straight/curved, waterproof/non-waterproof and some other special +2, +4, +8 (on demand) with power PIN connectors, which are added separately The power PIN can be used for larger current power supply.
