Termination Technique

Hi All ,

Please give me the details about the series and parallel terminations used in PCB
what are the necesscity of the terminations used in PCB?
Where we place them ?
please clarify.

Thanks

Re: Termination Technique

Adding a proper termination is a way to reduce terminations. Different5 types of terminations are
Dual clamp
High Clamp
Low Clamp
RC
Series
Shunt

Termination Technique

Basically the terminations are used to avoid the reflection of signals. As per the maximum power transfer theorem, the maximum power will be transfer when the impedance of the both source and destinations (load) are equal. In the case of PCB, the terminations are used to match the impedance. Two types are mostly used: Serial and parallel terminations.

The serial terminations are placed near the source area and parallel terminations are placed near the destination (load).
