Abstract
Aspects for improving signal quality on high speed, multi-drop busses are described. The aspects include coupling a source device directly to multiple load devices, wherein there are no resistance components coupled in series between the source device and the multiple load devices. The aspects further include providing a spacing arrangement for the multiple load devices, wherein negative reflections are delayed to minimize deleterious efforts from the negative reflections. Through the present invention, the modified version of a commonly used bus topology achieves extended voltage timing margins in a high speed, multi-drop bus in a straightforward and efficient manner.
