Microchip Technology EV03V90A Ethernet Evaluation Board designed to demonstrate the capabilities of the LAN8830 Gigabit Ethernet Transceivers. This Ethernet Development System (EDS) daughter card enables modular attachment to the host boards with the EDS interface, such as EVB-LAN7431-EDS PCIe to RGMII Networking adapter allowing PC-based evaluation. The device supports source or client modes for ordinary and boundary clock operations and a transparent clock per the IEEE Std 1588-2008 specification. End-to-end and peer-to-peer link delay mechanisms, as are one-step and two-step operations, are supported.
