  2. Overview Bunch Veto μTCA Crate FEE 100 MHz Clock C+C Master C+C Fanout Slave FEE 4 FEE C+C Fanout FEE Start/Info/Stop Crate Processor C+C Fanout C+C Fanout Bunch Veto FEE Status 4 Trigger + Telegram ID 1-20MHz? Clock Trig/Data 5MHz Clock MINIMUM FANOUT REQUIREMENTS : 16 + Fanouts, expandable 3x Outputs ( diff. LVDS, STP/UTP ) 1x Input ( single line, level only ) Timing Receiver Timing Interface XFEL Other C+C

  3. Information / Questions & Answers -1- 1) TRIGGER “Telegram” from TR : same line TRIGGER, with Train ID & Pattern ID 2) FEE feedback line : Status only ( e.g. Normally floating high, pulled low by FEE when powered ), no other information 3) External clock input at other test sites :use PLL ( to ~ 1-20 MHz range input ) 4) Bunch Veto signal – synchronised to the 100MHz 5) Calibration Pattern distributed by LAN from RC 6) Veto Disable Pattern by LAN from RC 7) 100 MHz clock output : - max. jitter to be specified by users - programmable delay / step size to be specified 8) Output Clock / Start/Stop pulses phase relationship : - same cable length for all FEEs C+C

  4. Information / Questions & Answers -2- 9) Connection between C+C Master and FanOuts : - on custom backplane all signals / FEE feedbacks only ?? - use single or double FanOut layer ?? - TBD by C&C 10) C+C FanOut cards : - separate power on backplane => not TCA-intelligent cards ?? - separate ‘dumb’ FanOut cards and crate ?? - on / near detector => fewer cables ?? - TBD by C&C 11) LVDS connectors : - RJ45 – bulky, 4-pairs only, but can use 2x LEDs - Double-stack RJ45 – availability / height ?? - HDMI - size / more signal pairs / more grounds/shielding ?? - Double stack HDMI - size ?? - mini-HDMI ?? - TBD by C&C 12) No C&C System interface to MPS ( Machine Protection System ) 13) NO confirmation that the 5MHz PLL derived TR board clock is "clean" and has no glitches ??? C+C

  10. BUT ( there is always a ‘but’…. ) Just found…2x4, 2x6, 2x8 TYCO Stacked RJ45s for ATCA/AMC http://www.ttiinc.com/object/fp_tyco_stackedrj45.html C+C

  11. Stacked RJ45 Modular Jacks for AdvancedTCA Tyco Electronics Stacked RJ45 Modular Jacks for AdvancedTCA Tyco Electronics has released new stacked RJ45 modular jacks designed to meet both AdvancedTCA and AMC standards. The offset has been designed to fit the faceplate and board layout in AdvancedTCA and full size AMC modules, while providing the port density of the stacked configuration These jacks are shielded and include panel ground springs for EMI containment. • Offset designed to meet both ATCA and AMC standards • Category 5 performance • Press-fit termination to the board • Available in 2x1, 2x4, 2x6, and 2x8 configurations • Available with various LED options C+C

  12. Modular Jacks 2x8 OFFSET STACKED W/GROUND CLIP Tyco Electronics / AMP Part No: 1888654-3 Modular Jacks 2x8 OFFSET STACKED W/GROUND CLIP NOT YET RELEASED FOR PRODUCTION - NOT YET AVAILABLE http://www.ttiinc.com/page/search_results.html?step=buyNow&searchTerms=%201888654-3+Tyco C+C

  13. Double Possible Best Option…..: COMBINED MASTER / FANOUT ? 16x FanOuts 1x Input C+C

  14. End….. C+C
