Hi Team,
Posting on behalf of our customer.
We are currently working on a design that utilizes Power over Ethernet (PoE) and is required to comply with IEEE 802.3-2022. Based on our system constraints, we have evaluated and documented multiple architectural approaches, which are attached for your reference.
Among these, the first approach is our currently selected and planned architecture for execution. In this approach, we are using a Ethernet to PCIe Gen3 single-lane interface, with the DS80PCI102 selected as the PCIe redriver.
We would appreciate your review and feedback on all the proposed approaches. In particular, we are seeking your inputs on the suitability and validation of the selected redriver for our intended use case w.r.t distance. If you believe an alternative redriver would be more appropriate, please feel free to suggest suitable options.
Additionally, for the first (currently selected) approach, we are encountering challenges related to connector and cable selection. We would welcome your recommendations for a more robust solution from a signal-integrity and compliance standpoint, especially with respect to IEEE 802.3-2022 requirements.
At this stage, the approaches are still under discussion due to routing constraints and the complexity arising from the signal travel distances for both PCIe and MDI signals.
We look forward to your guidance and recommendations. I have attached the approach in this thread.
Regards,
Danilo
