Part Number: DS90UB953-Q1

We planning to use DS90UB953-Q1 Serializer with power over coaxial cable.

Can you please provide the power over circuit calculation?

Hello,

I can help with the implementation of a power over coax circuit but can you elaborate a bit on what information you are looking for?

Regards,

Nick

Hi Nicholas,

We are planning to give 12V for the power over Coax. Can you please give the calculation of Inductor and capacitor which can be used to isolate the signals and power.

Hello,

In the 953 datasheet there are actually recommendations for PoC networks along with capacitors and inductors. I would recommend to follow along with the datasheet examples and if needed try to simulate the high-speed channel and the affects of the PoC network.

Regards,

Nick
