VSC8541XMV-05

Overview

The VSC8541XMV-05 is a single-port Gigabit Ethernet copper PHY from the VSC8541-05 series, manufactured by Microchip Technology. It supports IEEE 802.3 standards including 10BASE-T, 100BASE-TX, and 1000BASE-T over Cat5 twisted pair media. The device provides GMII, RGMII, MII, and RMII MAC interfaces with configurable edge rate control. Key specifications include an operating temperature range of -40°C to +85°C, power supply voltages for VDDMAC/VDDIO (2.5V or 3.3V) and VDDMDIO (1.2V, 1.5V, 1.8V, or 2.5V), and support for Synchronous Ethernet and IEEE 1588 Precision Time Protocol. It features Energy-Efficient Ethernet (EEE), Wake-on-LAN, and ActiPHY power management.

Feature Summary

• Supports Synchronous Ethernet and IEEE 1588 time stamping for precise network synchronization.
• Integrates Energy-Efficient Ethernet (EEE) and ActiPHY power management states to reduce energy consumption during idle periods.
• Provides Start of Frame (SOF) indication capability specifically for the -05 variant to assist in packet processing latency reduction.

Applications

• Industrial Ethernet switches requiring robust connectivity and low power states.
• Network infrastructure equipment utilizing Synchronous Ethernet for timing distribution.
• Embedded systems needing IEEE 1588 precision time protocol support for synchronized operations.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to ensure compatibility with required voltage levels and temperature ranges. Confirm package availability and moisture sensitivity handling requirements prior to assembly. Cross-reference part numbers with official Microchip documentation to avoid substitution errors.

Selection Notes

Select this component when a single-port Gigabit solution with integrated RGMII/GMII interfaces is required. Ensure the host system supports the necessary voltage domains for VDDMAC and VDDMDIO. Consider the -05 variant if Start of Frame indication functionality is needed for optimized packet handling performance.
