Microchip Technology EV73E88A Evaluation Board
Microchip Technology EV73E88A Evaluation Board is a development platform for evaluating high-density Power over Ethernet (PoE) Power Sourcing Equipment (PSE) designs. The board combines the Microchip Technology PD77718 PoE manager and PD77010 PoE controllers to support 48 two-pair or 24 four-pair IEEE 802.3bt PoE ports. Designed for enterprise and industrial networking applications, the EV73E88A enables evaluation of advanced PoE power-management and control functions. The board interfaces with Microchip Technology VSC56xx, LAN969x, SparX-5i PCB135, and Laguna Time-Sensitive Networking (TSN) switch platforms, helping accelerate the development of next-generation Ethernet infrastructure equipment.
