Carrier to analog board1
  • Can we use smaller connectors since the number of data IOs per ASIC reduces from 24 to 10?
  • How are we going to prevent ePixHRM carriers to be connected in to the 100kfps digital board and vice-versa?
    • Options could be mechanical pins or change connector polarities
    • Or via serial ID (needs to have a database) via soft locks
  • Routes all power, data and control signals to/from the ASICs
Analog to digital board1External power supply
  • Distributes the 24V from the power connector
  • Routes data and control signals between the ASIC on the carrier and the FPGA on the digital board
External power supply
  • Should be on the bottom board (digital) because a pigtail is connected to it that is attached to the outside shell
    • If if was on the top board (analog) there's a risk of damaging the ASICs and their wirebonds on the carrier
Optical transceiver
  • Same as for the power connector
  • Place close to FPGA due to 25 Gbit/s signals
