Design Support


This application report describes design considerations for low-voltage differential swing (LVDS) multidrop connections. The report describes the maximum number of receivers possible versus signaling rate, signal quality, line length, output jitter, and common-mode voltage range when multidrop testing on a single LVDS line driver transmitting to numerous daisy-chained LVDS receivers. The LVDS receivers are wired to simulate a wire-wrapped or printed circuit backplane environment. The receivers are tested to monitor system response for different signaling rates and a varied number of receivers.
