Descripción
Sumario:The final implementation of the Synchronization and Link Board (SLB) used in the Calorimeter Trigger system of CMS is presented in this paper. The board allows the synchronization of electromagnetic and hadronic trigger primitives at the LHC frequency (40.08 MHz) and its transmission to the Regional Calorimeter Trigger using Vitesse electrical links at a rate of 1.2Gb/s. The system developed for the SLB production tests and commissioning of the full production (1300 boards) is also presented.
