RosenbergerHSD® is a homogeneous impedance-controlled interconnect system which directly addresses the high-speed data, low-voltage requirements of real-time automotive industry applications. Extremely compact and durable this 100 Ohm fully shielded interconnect system utilizes shielded twisted quad cables and features mechanical keying and latching for high connection retention, as well as coding to avoid misuse. Furthermore, these precision manufactured RosenbergerHSD® SF variants are ideally suited for process-safe and fully automated assembly by harness makers, facilitating a significant reduction in costs.

Its high data throughput performance while also preventing interference from crosstalk and external sources makes the RosenbergerHSD® cable and PCB connector system the perfect choice for LVDS cameras, USB connections and IEEE 1394 applications. In addition, it is well-suited to many other applications including those found in digital infotainment electronics and digital symmetrical networks – even radio base stations.

Star-Quad – Arrangement of Two Differential Pairs
From twisted-pair to "star-quad"

With a twisted pair, the conductors are twisted directly around each other. The greatest advantage of a twisted pair is that they mutually, and almost completely, cancel out the influence of external fields that might induce a voltage difference between both conductors. These properties are of particular interest from the point of view of electromagnetic compatibility (EMC).

The Rosenberger HSD® system has been developed consistently for "star-quad" cables with star-shaped stranding of pairs of twins. In this case, the four individual conductors are stranded directly in consideration of the symmetry of the star-shaped cross-sectional configuration, this allows a simpler and more cost-effective production, a smaller outer diameter and the possibility of an automated assembly process.
