This reference design provides a cost-optimized solution for 10 to 100 Mbps using the low-power Ethernet physical layer (PHY) DP83825 supporting 150-m reach over CAT5e cable which is beyond the standard Ethernet distance limitation of 100 m (328 feet). This design also demonstrates power delivery over Ethernet cable along with data communication using IEEE802.3at Type-1 (13 W) PoE-PD TPS23755 device with integrated primary side regulated flyback DC/DC controller. This reference design is pre-compliance tested for radiated emissions, ESDs and EFTs.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
