  • pls update shape of the mezzanine board
  • we don't need that many 12V connectors, single locking jack from Switchcraft is enough
  • pls use cheaper CMC filter, BNX02 is too expensive
  • we need following front panel connectors: 10MHz , PPS, RF, USB-C ; make sure the SMA plugs won't collide
  • don't forget about 5k1 resistors in USB-C, use low cost connector without high speed pins
  • on the other side we need 10MHz IN, PPS IN and 125MHz IN/OUT
