•  On which board does the power connector (TFM) go and which type (TFM-112, TFM-115, etc)? (update Connectors section)
•  Does the digital board need the analog ground (AGND)? (see 100kfps DAQ support system)
•  Route +6V or +24V between analog and digital board?
  •  If +6V: All first-stage converters (LT8648S) must be on one the board with the input TFM connector
•  For the 0.6V sink:
  •  Is it really +0.6V and sinking current that is needed?
  •  Has this been done before?
  •  Special LDO config needed? (see design note from Analog)
  •  

    Precision Current Sources and Sinks Using Voltage References

•  Can the DC/DC architecture be simplified? Some ICs not in stock, see DC/DC converters
  •  Replace LMZ31530 (30A) with TPSM5D1806 in parallel mode (12A) since Vcc_int is estimated at 7A?
  •  Replace LT1764 with LT3083 for simpler paralleling circuitry (see power graph)
•  Are the ASIC digital supply (G_DS_X) and I/O supply (G_IO_X) shared among all four ASICs?
•  Do we have the CML current consumption numbers?
•  Use FPGA transceivers for clocking the ASICs?
  •  One per ASIC?
•  Request components for Altium library (see Altium Missing Components section)
