TECHNIQUE FOR PROVIDING IMPROVED SIGNAL INTEGRITY ON COMPUTER SYSTEMS INTERFACE BUSES

摘要

An interface system for transmitting a pulse waveform signalbetween a host computer and a plurality of peripheral unitswherein such signal is transmitted on a dedicated bus, theperipheral units being connected to the bus in selected groupsthereof. Each group has a buffer unit connected between thegroup of units and the host unit, the buffer unit includingcircuitry for providing signal transmission in only onedirection, for controlling the final signal level of the signal,and for controlling the slope of the trailing edge of the signalso that signal degradation is minimized.
