Overview
The VSC8574XKS-05 is a quad-port Gigabit Ethernet PHY from the VSC8574 series, manufactured by Microchip Technology. It supports 10/100/1000BASE-T copper and 100BASE-FX/1000BASE-X fiber media standards. The device features four SerDes interfaces for dual media capability and integrates IEEE 1588 precision time protocol support. It operates within an industrial temperature range of -40°C to +125°C and utilizes a PBGA-256 package.
Feature Summary
- Supports Synchronous Ethernet (SyncE) and IEEE 1588 Precision Time Protocol for network synchronization.
- Integrates Energy Efficient Ethernet (EEE) functionality to reduce power consumption during low traffic periods.
- Includes VeriPHY cable diagnostics for automated twisted pair link verification.
Applications
- Carrier Ethernet switches requiring precise time synchronization.
- Industrial networking equipment operating in extreme temperatures.
- Telecommunications infrastructure utilizing mixed copper and fiber topologies.
Procurement Notes
Verify component authenticity through authorized Microchip distributors or official channels. Confirm that the specific ordering suffix matches the required industrial temperature grade (-40°C to +125°C). Ensure compliance with RoHS directives as specified in the datasheet before finalizing procurement orders.
Selection Notes
Select this model when a quad-port solution with integrated SyncE and IEEE 1588 capabilities is required. Verify that the host system provides adequate thermal management for the PBGA-256 package. Ensure the MAC interface supports QSGMII or SGMII protocols for proper connectivity.
Part Context
This component belongs to the VSC8574 family of high-performance Ethernet transceivers. It serves as a bridge between MAC controllers and physical media, supporting both copper twisted pair and optical fiber connections. The device is designed for robust performance in demanding communication environments.
Replacement Considerations
Consult the official Microchip discontinuation notification for the VSC8574XKS-04 variant. Verify pinout compatibility and register mapping if substituting with other members of the VSC857x series.
