2 2 23 April 2009C+C μ TCA Crate Timing Receiver Crate Processor 100 MHz Clock Start/Info/Stop Bunch Veto FEE Status C+C Master FEE C+C Fanout FEE 5MHz Clock Trigger + Telegram ID Bunch Veto 4 FEE 4 C+C Fanout Slave XFEL Timing Interface Other 1-20MHz? Clock Trig/Data Overview MINIMUM FANOUT REQUIREMENTS : 16 + Fanouts, expandable 3x Outputs ( diff. LVDS, STP/UTP ) 1x Input ( single line, level only )

3 3 23 April 2009C+C 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 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 - programmable delay / step size to be specified 8) Output Clock / Start/Stop pulses phase relationship : - same cable length for all FEEs - same cable length for all FEEs Information / Questions & Answers -1-

4 4 23 April 2009C+C 9) Connection between C+C Master and FanOuts : - on custom backplane all signals / 9) Connection between C+C Master and FanOuts : - on custom backplane all signals / FEE feedbacks only ?? FEE feedbacks only ?? - use single or double FanOut layer ?? - use single or double FanOut layer ?? - TBD by C&C - TBD by C&C 10) C+C FanOut cards : - separate power on backplane => not TCA-intelligent cards ?? - separate dumb FanOut cards and crate ?? - separate dumb FanOut cards and crate ?? - on / near detector => fewer cables ?? - on / near detector => fewer cables ?? - TBD by C&C - TBD by C&C 11) LVDS connectors : - RJ45 – bulky, 4-pairs only, but can use 2x LEDs - Double-stack RJ45 – availability / height ?? - Double-stack RJ45 – availability / height ?? - HDMI - size / more signal pairs / more grounds/shielding ?? - HDMI - size / more signal pairs / more grounds/shielding ?? - Double stack HDMI - size ?? - Double stack HDMI - size ?? - mini-HDMI ?? - mini-HDMI ?? - TBD by C&C - 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 ??? Information / Questions & Answers -2-

10 10 23 April 2009C+C BUT ( there is always a but…. ) Just found…2x4, 2x6, 2x8 TYCO Stacked RJ45s for ATCA/AMC

11 11 23 April 2009C+C Stacked RJ45 Modular Jacks for AdvancedTCA Tyco Electronics 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. 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 standardsOffset designed to meet both ATCA and AMC standards Category 5 performanceCategory 5 performance Press-fit termination to the boardPress-fit termination to the board Available in 2x1, 2x4, 2x6, and 2x8 configurationsAvailable in 2x1, 2x4, 2x6, and 2x8 configurations Available with various LED optionsAvailable with various LED options

12 12 23 April 2009C+C Modular Jacks 2x8 OFFSET STACKED W/GROUND CLIP Tyco Electronics / AMP Part No: Modular Jacks 2x8 OFFSET STACKED W/GROUND CLIP NOT YET RELEASED FOR PRODUCTION - NOT YET AVAILABLE

13 13 23 April 2009C+C Possible Best Option…..: Double 16x FanOuts 1x Input COMBINED MASTER / FANOUT ?
