  4. FEE/DAQ WS Mission Statement FEE/DAQ Workshop • Focus is on system aspects of the final system • Interim solutions, like n-XYTER, should only be covered in a 'lessons learned from' context. CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  5. FEE/DAQ WS Agenda FEE/DAQ Workshop • Monday • morning: TOF (PADI/GET4 readout) • afternoon: TRD/MUCH ('Gas'-XYTER readout) • Tuesday • morning: STS ('Si'-XYTER readout) • afternoon: MVD/RICH DAQ/FLES Full program and presentations seehttp://cbm-wiki.gsi.de/cgi-bin/view/DAQ/Workshop-2010-02 CBM Collaboration Meeting -- Walter F.J.

  20. FEE/DAQ WS STS Hit Rates per 128 Channel Chip Au+Au @ 25 AGev107 evt/sec • Very few chip in inner region have hit rate > 32 MHz • >90% of chips have hit rates in 2...16 MHz range Hit rate per chip Statistics SIM-Data: A. Kotynia CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  21. FEE/DAQ WS Is this enough space for: - 117 copper links - 10 opto converters - 10 ribbon fiber cables plus other services like - power distribution - control & monitoring - ,,,,,,, STS Quadrant STS-FEBs size of a post card 5 cm 6 cm CAD: S. Belogurov et al CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  22. FEE/DAQ WS Compact electro-optics Converts I LightABLE from ReflexPhotonics Optically enabled FPGA Use MT connector: 12 x TX or 12 x RX or 4xTX and 4xRX Optically enabled ASIC Claim for 12 channels: 4 cm2 footprint 3 mm height Extracted from ReflexPhotonicsWhite Papers and Presentations CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  23. FEE/DAQ WS Some Data on Fiber Ribbon Cable • Assume 12 fiber ribbon cable • very compact, 20 mil pitch • cable cross section: 2.3 x 5.1 mm • Assume MPO/MPT connector 2.3 mm 5.1 mm Pictures from GORE CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  24. FEE/DAQ WS STS Interface Converter Board • Proposal for STS interfacing • 2m copper twinax x1, x2, x4 or x8 • copper => optical on Postcard 12.7cm x 8.9cm • Conversion to optical signals with AOCs • Does electrical and AOC connector fit on one Postcard ? • Connector density analysis AOC connectors twinax connectors Passive Board Postcard miniHT connector twinax connectors Slide: U. Bruening

  25. FEE/DAQ WS STS Link & Ribbon Cable Distribution Au+Au @ 25 AGev107 evt/sec • All STS data can be transported by ~280 ribbon cables • Corresponds to 34 cm2 cable cross section FEB&Cable Statistics 48 bit message Proviso: link counts likely to go up to account for more background,overhead, head room,....

  26. Where to locatefast serializers andopto-converters ? CBM Collaboration Meeting -- Walter F.J. Müller, GSI

  27. DAQ/FLES WG Data Aggregation on separate chip - Communication hub • Motivation: • Data Aggregation: In most cases 2,4, or 8 CBM-XYTER chips (FEBa2, FEBa4, FEBa8, resp.) can be aggregated to fill a 2.5 Gbps link • Increase the bandwidth available per link • Reduce the number of Optical Links • Schemes: • Embedded (aggregation integrated in CBM-XYTER) • Data aggregation and Traffic Managementwith a separate Communication Controller Asic  • Clock Distribution • Slow control traffic • Data Readout traffic Communication ‘hub’ 15th CBM Collaboration Meeting 6 Slide: P.
