Note

The tasks and questions below should be looked at as soon as possible since they might be blocking

  •  What's the expected operating temperature range?
    •  -25C → +50C
  •  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?
      •  No, the 20A version should be available (LMZ31520)
    •  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?
    •  Gang is saying around 20mA (15mA + 30% LVT) per ASIC TX Transceiver (for all frequencies). ASIC RX consumption is negligible 
    •  Update power estimation table with these numbers
  •  Request components for Altium library (see Altium Missing Components section)
    •  Connectors have been requested on 2023-08-28
    •  Other ICs
