5.1 Design Considerations

  • Unless otherwise noted in the data sheets, ensure <70 pF lumped capacitance for optimal performance per the data sheet’s recommended data rates.
  • Additional parasitic capacitance is added from trace length and connectors.
  • Additional loading impacts signal integrity at faster data rates.
