• The preamp is sampled at 100MHz into a ring-buffer. On-board trigger and control
let the user select which data is to be output. The analog pre-prosessing greatly
recudes system power consumption
• 121channel version available off-the-shelf.
• Optionally a 12 bit SAR ADC can be added to the ASIC.

28. Work flows
Off-the-Shelf, days to a couple of weeks
Custom development (6-18months). Cost is strongly dependent of level of verification and validation
required.

29. Applicable standards
• Strongly dependent of the application requirement. Tayloring of
standards can reduce cost of compliance.
• We have worked to:
 MIL-STD 883 test method standard for microcircuits
 IEC 60601 electric safety
 ESA ECSS Space product assurance:
• ECSS-Q-ST-60-02C ASIC and FPGA development
• ECSS-M-ST-10C Project planning and implementation
• ECSS-Q-20 Space product assurance - Quality assurance
• ECSS-Q-ST-30-02 Space product assurance – Failure Mode,
effects (and criticality) analysis (FMEA/FMECA)“
• And others from the ECSS series
