Overview
The VSC8531XMW-02 is a single-port Gigabit Ethernet copper PHY manufactured by Microchip Technology. It supports data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s over Cat5 twisted pair media. The device interfaces with MACs via RGMII or RMII protocols. Operating voltage ranges from 1 V to 3.3 V depending on the specific power domain (VDDMAC, VDDIO, VDDMDIO). It operates within a temperature range of 0°C to +125°C and is housed in a QFN-48 package.
Feature Summary
- Supports Energy-Efficient Ethernet (EEE) for reduced power consumption during idle periods.
- Includes ActiPHY power management states including low power and link partner wake-up capabilities.
- Features VeriPHY cable diagnostics for testing and fault detection on the physical medium.
- Provides Wake-on-LAN and SecureOn functionality for remote system activation.
Applications
- Managed and unmanaged Gigabit Ethernet switches
- Industrial networking equipment requiring extended temperature operation
- Access points and network infrastructure devices
Procurement Notes
