VSC8574XKS-10

Overview

The VSC8574XKS-10 is a quad-port dual media Gigabit Ethernet PHY transceiver designed for Carrier Ethernet applications. It integrates four 10/100/1000BASE-T copper transceivers and supports SGMII and QSGMII MAC interfaces. The device features IEEE 1588v2 timestamping, EcoEthernet 2.0 power efficiency modes, and integrated temperature monitoring. It operates with 1.0 V core and 2.5 V I/O supplies in a 17 mm × 17 mm PBGA package.

Feature Summary

• Supports single and two-step IEEE 1588v2 time stamping over encapsulated links including MPLS and PBB
• Integrates four dual media copper/fiber ports with unidirectional IEEE 802.3ah support
• Provides recovered clock outputs with programmable clock squelch control for Synchronous Ethernet solutions
• Features EcoEthernet 2.0 technology with ActiPHY automatic link powerdown and PerfectReach intelligent algorithm

Applications

• Wireless backhaul systems
• Carrier Ethernet cellular base stations
• Industrial automation systems

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm pinout, packaging, or environmental compliance variations. Confirm current production status as product lines may undergo discontinuation notices. Ensure compatibility with existing system voltage requirements of 1.0 V core and 2.5 V I/O supplies before procurement.

Selection Notes

Select this component for designs requiring precise timing synchronization via IEEE 1588v2 and Synchronous Ethernet. It is suitable for high-density layouts due to its compact 17 mm × 17 mm package. Consider its low EMI line driver and integrated AC-coupling capacitors for simplified PCB routing in carrier-grade networking equipment.

Part Context

The VSC8574 belongs to the VSC8574 series of Quad Port Dual Media GbE PHYs from Microsemi (now Microchip Technology). This series targets carrier-class applications needing robust timing and redundancy. It serves as a key interface between MAC processors and physical Ethernet media in complex network infrastructure.
