Overall Structure & Notes
️· BOM Format: All three documents follow a similar format: Item, Quantity, Reference Designator (Ref Des), Value, Package, Description, Manufacturer (MFG), Part Number.
️· "Do Not Install" Note: A consistent note highlights that certain components are *not* to be installed.
️· Note Regarding Termination: All three mention an attenuation factor of three when using a 50-ohm termination resistance.
️· Legal Disclaimers: Extensive legal disclaimers are provided at the end of the NCS2540 BOM document.
