VSC8489YJU-02

Overview

The VSC8489YJU-02 is a dual-channel 10 GbE SerDes PHY manufactured by Microchip Technology. It converts RXAUI/XAUI host interfaces to SFP+ or 10GBASE-KR backplane connections. The device supports 10G LAN, 10G WAN, and 1GbE operation modes. Key electrical parameters include a data rate of 10 Gb/s, power supply voltages of 1 V and 1.2 V, and an operating temperature range from -40°C to +110°C. It utilizes an FCBGA-196 package for surface mount installation.

Feature Summary

• Supports conversion between RXAUI/XAUI host interfaces and SFP+ or 10GBASE-KR line interfaces.
• Integrates a Physical Medium Attachment (PMA) with a VScope input signal monitoring integrated circuit.
• Includes a WAN Interface Sublayer (WIS) for SONET/SDH section, line, and path overhead processing.
• Features a 10G Physical Coding Sublayer (PCS) supporting 64B/66B encoding and decoding.

Applications

• Dual channel WAN/LAN/backplane connectivity
• SFP/SFP+ application modules
• Backplane equalization systems

Procurement Notes

Verify the component status as End-of-Life (EOL) through official Microchip channels before design finalization. Confirm that the specific ordering suffix matches the required pinout and functionality. Ensure compliance with moisture sensitivity levels during storage and handling procedures.

Selection Notes

Select this component when a dual-channel PHY is required for converting XAUI/RXAUI signals to SFP+ or KR backplanes. Consider the thermal specifications and the FCBGA-196 package constraints for PCB layout. Verify support for synchronous Ethernet and specific management interfaces like MDIO or SPI if required by the system architecture.
