Description
This reference design implements a powered device (PD) to demonstrate Power over Data Lines (PoDL) in automotive applications. The design uses a DP83TG720S-Q1 1000MBit/s single-pair Ethernet (SPE) PHY with the option to switch to the DP83TC812S-Q1 SPE PHY for 100MBit/s operation. A coupling and decoupling network is used to split the data and power on the single-pair ethernet (SPE) cable.
Features
Capable of 1000Base-T1 automotive EthernetFootprint compatible to our 100Base-T1 SPE PHYThis design features the implementation of the powered device to be powered via the single-pair ethernet cableAutomotive qualified filter network for power coupling and decoupling with reverse polarity protectionImplementation of PoDL according to the automotive market requirements by reducing cost and complexity of the implementation
