VSC8572XKS-02

Overview

The VSC8572XKS-02 is a dual-port Ethernet PHY supporting 10/100/1000BASE-T standards with integrated Synchronous Ethernet and IEEE 1588 precision time protocol. It features QSGMII, SGMII, and RGMII MAC interfaces for flexible system integration. The device operates within a voltage range of 950 mV to 1.05 V and supports data rates from 10 Mb/s to 1 Gb/s. Designed for surface mount installation, it utilizes a PBGA-256 package (17x17 mm). The component functions reliably across an operating temperature range of 0°C to +125°C.

Feature Summary

• Supports Ring Resiliency technology allowing seamless switching between master and slave timing without link interruption.
• Includes an IEEE 1588 timestamping engine for precise synchronization in boundary clock and transparent clock applications.
• Integrates Energy Efficient Ethernet (EEE) capabilities to reduce power consumption during periods of low network activity.

Applications

• Carrier Ethernet access networks requiring high reliability and synchronization.
• Telecommunications infrastructure utilizing Synchronous Ethernet protocols.
• Industrial automation systems demanding precise time distribution via IEEE 1588.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required interface configurations and environmental ratings. Confirm that the PBGA-256 package dimensions align with the target PCB footprint. Check for moisture sensitivity levels and reflow soldering profile requirements prior to assembly.

Selection Notes
