  1. La carte DIF pour DHCAL(proto au m2 et au m3) Sebastien Cap, Julie Prast ( LAPP) Christophe Combaret (IPNL)

  2. Architecture of the DIF board DIF Power Supplies +/-5V 3.3V 2.5V ….. LDO Mezzanine Monitoring JTAG USB FPGA ASIC Config ASIC read DAQ interface Slow control SLAB LDA (HDMI) EP3C16F484 DAQ0 (SCSI) ADC HARDROCs analog output DIF The DHCAL DIF Board for the m2 and m3 prototype

  3. The DHCAL DIF Board • Separated from the slab for more flexibility. • Handle slab  the nb of HardRoc (up to 100). • Compatible with the DIF Task Force. • Interfaces with : • The final DAQ (LDA, …) • The analog DAQ • Neighboring DIFs. • PC through USB for standalone tests and debugs. • Handle HardROC power cycling. • Compatible with the ASIC of IPN Lyon. • High voltage is not foreseen. The DHCAL DIF Board for the m2 and m3 prototype

  4. Samtec FSH/ SFMH ? Interface with the SLAB SLAB • Use of a small intermediate board, which is specific to the FE ASIC and ASU. • The DIF can be used : • Whatever the FE ASIC. • Whatever the slab (RPC, uM) • Whatever the slab to slab connection. • Whatever the subdetector ? • 1rst ASU is the same as the others. • Common DIF to intermediate board interface between sub detectors (same connector, same pinout). DIF Intermediate board Connector to be chosen. No special constraint. Connection with the slab is the same as the one between 2 ASUs. 0 Ω resistor, … The DHCAL DIF Board for the m2 and m3 prototype

  5. Status and Agenda • Electrical schemes being finalized . • 90% done. • CAD well advanced (Merci Sebastien). • VHDL code is started. • Help of Guillaume Vouters between March and August. • Software tests and acquisition part is studied by Christophe C. • First prototype is awaited for May. • Main tests should be performed before summer. • Board available for M2 and M3 prototype.
