6. Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – March 2007 6 Firmware: - PLL and Clock Generation 40MHz; - T1 Commands; - Internal or External Trigger - DATA Input Buffer (FIFO); - Synch. With DATA Valid - TRIGGER Input Buffer (FIFO); - Use also for Trigger – CC logic - DATA and TRIGGER Output Buffers; - GOH Modules Control; - I2C interface Modes: - Internal Trigger/Commands and Pattern; - External Trigger/Data from VFAT Hybrids; - I2C Control Current Status (2) Test System in H8 now is: - Capable to Control and Readout “T2 Hybrid” and “RP Hybrid”; - Optimized for max of 4 fibers (4 x 16 VFAT Data Outputs);

7. Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – March 2007 7 Test System (in my office) Overview, Block Diagram, Characteristics This System now is: - Capable to Control and (with FPGA code modification) to Readout the “T2 Hybrid” and “RP Hybrid”; - Trigger Commands and Clock are I2C programmable; - Simple “USB I2C Controller” (from MIC group) to “TOTEM Setup” and FTDI Software; Up to 2 RP Hybrids T2 Hybrid VFAT Emulator + Transition Board Control / Readout PC Up to 16 T2 Hybrids I2C USB Adapter I2C USB FTDI program

8. Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – March 2007 8 Conclusions (1) TOTEM System in H8: - Capable to Control and Readout “T2 Hybrid” and “RP Hybrid”; - Optimized for max of 4 fibers (4 x 16 VFAT Data Outputs); - Complex and needs min. 2 persons (hardware + software) to run it: - Stable for short runs, but never tested for long (days for example); - Has unique hardware components temporary build (DOHM for example) to satisfy Test Beam ‘06 requirements; - Run only one time with T1 detector; - Inconvenient to test the hybrids - space, cleanness, store, materials, tools Test System for the Hybrids (T2,RP)? - Simple, portable and easy to use system is needed; - How much effort to build it (hardware + software) and when? - Ideas and proposals - do be discussed

9. Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – March 2007 9 Conclusions (2) TOTEM Electronics – now exist priorities as design of: - RP Motherboard + Mezzanines; - GEM Motherboard; - 11-th Card; - DOHM Card, etc…; - Testing of all this TOTEMINO ’07: - Electronics is very dependent from the goals foreseen (for example); - How many detectors? - How many channels per detector? - What we want to test?
