Design Considerations & Notes:
- Ensure board layout follows recommended footprint and shield grounding as per datasheet.
- Pay attention to current rating (720 mA @ 57 V) if your PoE design pushes high power scenarios (e.g., PoE+ devices).
- Operating temperature limited to 0 °C–70 °C; if your design runs hotter (industrial/extended temp) check suitability or derate.
- When designing EMI compliance and signal integrity, use the specified magnetics and test for insertion/return loss, crosstalk per data.
- Verify LED footprint and tab orientation (green/yellow LED option) to match your board layout.
