What is the primary purpose of using differential pairs in high-speed signal routing on a PCB?
easy🧠 Conceptual Q1 of 15
Step-by-Step Solution
Solution:
Step 1: Understand differential pairs concept
Differential pairs consist of two traces carrying opposite signals to cancel noise.Step 2: Identify the benefit in high-speed routing
This arrangement reduces electromagnetic interference and improves signal integrity.Final Answer:
To reduce electromagnetic interference and improve signal integrity -> Option AQuick Check:
Differential pairs purpose = Reduce interference [OK]
Quick Trick: Differential pairs cancel noise by carrying opposite signals [OK]
Common Mistakes:
MISTAKES- Thinking differential pairs increase PCB size
- Assuming differential pairs simplify layout
- Believing differential pairs reduce manufacturing cost
