Waveform distortion due to reflections in high-speed digital signaling is a classical issue of the signal integrity especially for the multi-drop transmission system. In general, the reflection characteristics and improvement measures of the multi-drop transmission strongly depend on the topology of the system in question, such as bus-configuration, star, ring, and so on. In this paper, we discuss a method of RCL (Reflection Compensation Line), formally reported in [6] as a reflection cancelling scheme, that can be applied to the bus-type multi-drop transmission system, whose length of main bus segments and stub lines are all isometric. Assuming practical application of our RCL technique to high-speed digital signaling, data rate of over 10Gbps, the optimal set of transmission parameters are deduced by means of numerical optimization algorithm, and the performance of the RCL is discussed.
