FIB Transition Module (FTM)

Features
  • Single Width 9U transition module 
  • Signal translator for FIB to Port Card communication 
  • Supports two Port Cards with ten data channels 
  • Two versions: One for copper data cables and one for fiber optic data cables 
Description

The FIB_TM card is designed to operate mechanically as a VME transition card in a card slot directly behind the FIB and to electrically translate signal levels for the FIB. The FIB is a 9U X 400mm VME board that receives and process system commands from the Silicon Readout Controller (SRC) and passes encoded control information to the port cards within the SVX detector. The FIB also takes data from the Port Cards and transfers the data to the level two data collection buffers or VME Readout Buffers (VRB). The FIB_TM performs electrical signal translation for the FIB board of both received and transmitted signals. An additional benefit of this separation of circuitry is that the FIB can adapt to different versions of Port Cards as the development of the SVX chips and Port Cards continues. The FIB , Port Card and VRB specifications are available as separate documents.

At this time, two versions of the FIB transition module exist. The first one, which is pictured here, was built while the DOIM fiber optic links were still under design. Early test stands used copper cables to carry the data from the port card to the FIB subrack. Therefore, the first FIB_TM is called the copper version or FIB_TM_CU. The production version is called the fiber optic module or FIB_TM_FO. Most documentation points to the Fiber Optic production version.
