VSC8501XML

Overview

The VSC8501XML is a single-port Ethernet PHY supporting 10/100/1000BASE-T standards. It features integrated line-side termination and RGMII timing compensation to reduce board space and EMI. The device supports Synchronous Ethernet with recovered clock output and Ring Resiliency for master/slave switching without link drops. Power management includes EcoEthernet v2.0, IEEE 802.3az EEE, and Wake-on-LAN via magic packets. Fast link failure indication operates in under 1 ms. It interfaces via RGMII/GMII/MII at 2.5V or 3.3V and operates from -40°C to 125°C junction temperature in a 135-pin QFN package.
