Uli Schäfer 1 JEM1: Status and plans Hardware status Firmware status Plans
Uli Schäfer 2 JEM1 16 x 6-channel de- serialisers : SCAN921260 on 4 Input daughter modules w. XC2V1500. G-link / Opto daughter module Jet and Sum Processors XC2V2000 (BF package). Configuration : SystemACE 88 pair VMEVME each 165 pins FIO 60 bit @ 80Mb/s TTCdec CAN System ACE 3 x 40 bit @ 40 Mb/s DES Input 2 B 1 A 0 V 60 40 Input 5 E 4 D 3 C Input 8 H 7 G 6 F Input -- 10 X 9 W DAQ/Timing/VME To JMM G G Jet R S T U Sum DAQ To SMM ROI Opto clock mirror
Uli Schäfer 3 JEM1 H/W Status Input daughters: 4 modules available 2 fully working (PCB ageing problems) Main board: 1 module available Fully working. Few bug fixes required (2 tracks missing, 1 pull-up). CAN under test. Compatibility ? Flash configurator not yet successfully operated (cfg read error) G-link daughters: 1 (electrical) module available, in-house assembled, re- worked after RAL test. fully (?) working
Uli Schäfer 4 JEM1 firmware status (energy sum / control) Previous JEM0 functionality fully implemented Latency reduction (energy path) ~3 ticks TTCdec : I2C control added TTCrx ID via GeoAdd short broadcast support CPM-style spy memory control (continuous spy, wrap at 255) Playback / spy VME-controlled, use broadcast to reset pointers Flash configurator (ACE) mapped into VME VME control (including configuration) faster and more reliable To be done: Support for CAN (?)
Uli Schäfer 5 Plans : JEM1 Prototype production Make a total of 4 JEMs for slice test & beam test Main board: 3 PCBs available Components available Assembly at Rohde & Schwarz starting next week (?) Input daughter modules (+16): Active components (LVDS/Xilinx) available Slot for PCB production & assembly at Rohde & Schwarz: ? G-link daughter modules: Components available Slot for PCB production & assembly at Rohde & Schwarz: ? Total of four JEMs available for tests early August
