This project is part of an ATLAS Super LHC research and development effort This project is part of an ATLAS Super LHC research and development effort At the LHC data will be processed at approximately 1 Terabit/second At the LHC data will be processed at approximately 1 Terabit/second Data is transferred over a large number of optic cables Data is transferred over a large number of optic cables Due to the large number of connections it is desirable to know the quality of the transmission signal Due to the large number of connections it is desirable to know the quality of the transmission signal ENTER THE SNAP 12 SNOOPER Motivation

What Does This Device Do? Functionality Signal Detect Test- This will check to see if a signal is being sent through the fiber optic cable. Signal Detect Test- This will check to see if a signal is being sent through the fiber optic cable. Synchronization Test- Checks that the information being transmitted is in the proper format. Synchronization Test- Checks that the information being transmitted is in the proper format. BIST Test- Industry standard test to check for errors in the coding of the output information BIST Test- Industry standard test to check for errors in the coding of the output information

FPGA Design

Conclusions We have developed a SNAP-12 Snooper that checks the signal integrity on Snap-12 fibers My role included all aspects- design, layout, firmware, and testing. Signal Detect Test – successfully implemented and verified Synchronization Test – firmware completed BIST Test – firmware in progress Plan is to use in the field by the summer of 2009
