| Abstract: |
| PoE(Power over Ethernet) is the technology used for both power supply and data transfer over 4 twisted pairs. With the approval of IEEE 802.3af,PoE is used widely in different network-based products because of its conveniency and low-cost. Using power sourcing equipment power manager TPS 2383 and powered device power interface switch TPS 2370 produced by TI Co.,a solution of PoE based on IEEE 802.3af is introduced,including system structure,features,HW frames,functions and their implementation. |
