Terminating transmission lines: Option4

• Differentially terminate the line

  • Termination as good as option1
  • Advantages
    • Can distribute gates along line
    • Differential signals
    • Low crosstalk
    • Don’t need contiguous ground plane
  • Disadvantages
    • High driver power
    • Need differential receivers

• Note: Great for buses

  • Put terminations at both ends of bus
  • SCSI uses this approach
