D-Sub, D-Shaped Connector Terminators

Products in this family are specialized connectors that are based on the D-subminiature pattern. These connectors are named as such due to their D-shaped outline and the high interconnect density they offered when they were first introduced. However, they differ from standard connectors of this style in that they incorporate one or more resistors or other circuitry between specific connector contacts. The addition of resistors or circuitry within these connectors serves a specific purpose in high-speed communication applications. One of the main benefits is the reduction of signal reflections. In high-speed data transmission, signal reflections can occur when the impedance of the transmission line changes abruptly at the point of connection. These reflections can cause signal degradation, resulting in errors and reduced signal integrity. By incorporating resistors or other circuitry between selected connector contacts, these specialized connectors help mitigate the occurrence of signal reflections. The circuitry is designed to match the impedance of the transmission line, ensuring a smooth transition of signals and minimizing reflections. This improves the overall performance and reliability of high-speed communication systems. It's worth noting that the exact configuration and specifications of the resistors or circuitry may vary depending on the specific application requirements. The connectors may be available with different resistance values or other circuit components tailored to suit different communication protocols and signal requirements. In summary, the products in this family are specialized connectors based on the D-subminiature pattern. They incorporate resistors or other circuitry between selected connector contacts to reduce signal reflections in high-speed communication applications. This helps maintain signal integrity and improves the overall performance of these systems.
