Dear Team,
Below is the PoC circuit.
My questions are given below.
- Why 3 ferrite beads (FB1,FB2,FB3) are connected in series.
- How to design these ferrite beads
- Why there is a resistor connected in parallel with inductor(R1 & L1)
Regards
HARI

Hi Hari,
Thanks for reaching out with this question.
For technical details regarding the usage of PoC, you may find it helpful to consult this PoC application note which discusses the usage of PoC with FPD-Link ADAS devices.

Hi Thomas,
Thank you for your reply.
I go through the material you suggested. It provides a general overview of PoC.
Does not contain any design calculations.
If you see the below image you can see that the inductor value is 10uH,how they arrived 10uH why not 1uH or 100uH.
I would like to see the math behind the Bead selection ,Inductor selection and the parallel resistor selection.

HARI
Hi Hari,
With regards to the specific details of network design such as inductor and resistor selection, it would likely be helpful to reach out to a passive component vendor such as Murata, Coilcraft, or TDK to help with these questions. We collaborate with these vendors in the development of the networks which we recommend for our devices.
Best,
Thomas
