Abstract Increasing the number of available slots and performance of a system is a desired goal in many communications market segments. Between exercising the limits of physical backplane layouts and coaxing backplane transceivers to their electrical limits, the achievable speeds to date have been less than stellar. GTLP interface technology allows for an incident-wave switched backplane that provides superior performance and slots over previous, less capable technologies. This paper will demonstrate how to implement GTLP in heavily-loaded backplanes with optimized signal integrity. Issues discussed include proper termination selection, the effects of stub lengths, impedance choices, and related items. The results of both intensive simulations and actual measurements will be presented, based on an actual case study. The audience will benefit from this paper by learning how to extend the capabilities of their GTLP designs. While the focus is achieving the highest speed backplane possible with the maximum number of slots, this must be done with good signal integrity, noise and timing margins in mind. ->This paper is available from NESA for $15.00 to cover management costs.
