  General discussion
  
  Speakers: Adam Huddart (Science and Technology Facilities Council), Che Sum Tse (University of Birmingham UK), Georg Viehhauser (member@ox.ac.uk;staff@ox.ac.uk), James Julian Glover (University of Birmingham (UK))
  - a) Update on CB
  - b) Update on FIB
    
    Full list of desired connections on FIB:
    
    Serial powering (from Control Room):
    
    I_in.
    
    I_out.
    
    CB-to-FIB:
    
    3 x diff pair for FPC S/Cs (6 wires).
    
    VTRx+ power (2V5 domains could be supplied by 1 source, GND could be shared for all domains) (3-6 wires).
    
    1V2 Tx domian (VCCT1V2).
    
    2V5 Tx domain (VCCT2V5).
    
    2V5 Rx domain (VCCR2V5).
    
    GND needed.
    
    VTRx+ I²C (share GND with power domains?) (2-3 wires).
    
    SCL.
    
    SDA.
    
    Laser driver controls (2 wires).
    
    Reset.
    
    Disable.
    
    RSSI (Rx current monitor) (1 wire).
    
    VTRx+ thermistor (2 wires).
    
    2 terminal interface.
    
    Voltage sense (for VTRx+ domains) (3-4 wires).
    
    1V2 domain.
    
    Shared or separate 2V5 domains?
    
    GND sense (to account for V-shift on both rails).
    
    2 SP wires needed.
    
    Minimum of 19 wires (up to 24) between CB and FIB.
    
    Minimum only includes 1 x GND wire (we probably want more)!
    
    The VTRx+ has 25 pins that would be fed to the CB (+2pins/fibre=10 and 5N/C on a 40pin connector). See page9 of https://edms.cern.ch/ui/file/1719329/1/VTRxPlus_spec.pdf.
    
    12 GND pins.
    
    2 pins/voltage domain (6 pins total).
