Description
There has been a move to replace the fieldbus in automotive and industrial applications to a two wire Ethernet based system, increasing the data throughput in addition to simplifying device management by using a single physical layer protocol. In response, the IEEE association released amendments detailing Single Pair Ethernet (SPE) along with a protocol to inject power over this system, reducing the cost of running power lines. The new specification covering a method to inject power over SPE is known as Power over Data Lines (PoDL).Although Silvertel has a history of making Power over Ethernet (PoE) modules, due to the relative infancy of SPE and more so it’s limited deployment into everyday applications, Silvertel does not currently produce any modules designed to operate to the PoDL specification. However, for a proprietary implementation, this application note covers the use of Silvertel’s existing PoE modules to provide power to a system using SPE.
Features
- Programmable Output power limit up to 75W
- Compliant with IEEE802.3bt*, IEEE802.3af and IEEE802.3at specifications.
- Small SIL package size - 53mm (L) x 14mm (H)
- Low cost
- Minimal (low cost) external components required
- Over-current and short circuit protection
- Industrial Temperature Range
- Silvertel “design-in” assistance
Typical applications
- PoE over SPE
