JEM Status and plans Production modules Status Plans

JEM: Status and plans • Production modules • Status • Plans Uli Schäfer 1

JEM 1. 3 (production) • Sum processor XC 2 V 2000 • Jet processor XC 2 V 3000 • 4 input modules (IM) v 1. 1 (XC 2 V 1500, SCAN 921260) • TTCdec module • Control Module (CM) v 1. 3 • CAN • VME control • Fan-out of configuration lines • G-link readout module (RM) v 1. 2 Uli Schäfer 2

From pre-production to production • Pre-production: • 4 JEMs, 16 input modules, 4 G-link modules • Yield : ~75 %, re-work and insufficient cleaning thereafter • Tests concluded in first week of September • Production: • 41 JEMs, 160 input modules, 41 G-link modules, 45 control modules • Modifications wrt pre-production modules: • JEM - minor modifications : silk screen, pads for CLKdes 2 terminators (due to insufficient drive strength of on-TTCdec PLL), reduce bypass capacitance on 3. 3 V supply (now 17*68µF) due to crate supply oscillations • G-link and input modules: no modifications Uli Schäfer 3

Module production, so far… • September 12: pushed the button for production • 3 rd week of October: “Module production will take until Nov. 24” (JEM main boards), but no problems reported. • October 27: “input module PCBs have been manufactured with more than 20 % impedance error” need another production run (require 10% tolerance) • October 30: PCB production JEMs and input moules (re-) started • November 6: Production of input modules hasn’t actually been started yet. No information on main boards so far. Delivery of input modules will be last week of November • November 8: • Control and G-link modules will be ready early next week. • JEM PCBs have been made. 33 out of 41 are usable and will be assembled immediately. Remaining ones will be manufactured and assembled at a later date • Input module PCBs due Nov. 17, will try and have assembly done by last week in November Uli Schäfer 4

Acceptance tests JTAG B/Scan ready for tests: • Adapters • Annotated netlist Basic link tester for input modules LVDS inputs (lock / no lock) available Basic G-link tester consisting of O/E converter + oscilloscope (fill frame) Uli Schäfer 5

System tests Mainz • • • Production crate now available at Mainz No more problems with triple. E mechanics One old VMM One old TCM no CMMs 6 U crate with TTC system, one LSM, DSS • For test plans see Markus presentation: • LVDS tests (firmware error detection and via spy) • FIO tests (firmware error detection) • G-link tests (software error detection via DSS) • JEM rtdp tests (including algorithms) via spy Full system tests with CMMs and ROD readout possible at CERN only… Uli Schäfer 6

Plans • Mid November: • Mechanical assembly of JEMs (front panels etc. ) • Power up and test all available modules individually (boundary scan) • Mount available daughters on main boards • ~ Last week of November: delivery of input modules • Boundary scan input modules and mount on JEMs (< 2 weeks) • System tests : ~ 2 weeks (partially overlapping) • Prepared to continue work on JEMs last week of December • Modules at CERN early January… Uli Schäfer 7
