Fast synchronous distribution network of data streams for RPC Muon Trigger in CMS experiment

The paper presents a design and realization of the fast and synchronous data transmission system for the RPC Muon Trigger in the CMS experiment. There is described a method of data distribution system design on the TriDAQ board. The solution takes into account the realization methods of particular building components of the involved transmission channels. The chosen solution enables signal distribution originating from the multi gigabit optical links. The data signals are transmitted from the RPC chambers to the trigger processors and to the data acquisition block. The distribution network was build using a differential standard of data transmission -- the LVDS (low voltage differential signaling system). The solution applied practically for building a dedicated PCB is described.
