Abstract
The impact of flip-flop metastability on the pipelined trigger for the CLAS detector at CEBAF has been studied. We find that the newest ECL flip-flops (ECLinPS) are much faster than older families (10H) at reso lving the metastable condition. This will allow their use in systems w ith asynchronous inputs without an extra stage of synchronizing flip-f lops.
