VSC8488XJU

Overview

The VSC8488XJU is a dual-channel 10 Gbps XAUI to serial transceiver with electronic dispersion compensation (EDC). It supports data rates of 9.95 Gbps WAN, 10.3 Gbps Ethernet, and 10.5 Gbps Fibre Channel. The device operates on 1.8 V and 1.2 V core power supplies. Typical power dissipation is 1 W per bidirectional channel. It features MDIO, two-wire serial slave, and two-wire serial master interfaces. The component includes adaptive FFE/DFE receivers and programmable multi-tap transmit pre-emphasis.

Feature Summary

• Integrates electronic dispersion compensation for SFP+ LRM applications and backplane compliance.
• Supports flexible clocking options enabling Layer 1 Synchronous Ethernet operation.
• Includes comprehensive BIST functionality with line and client loopbacks.
• Provides selectable lane ordering and failover switching capability.

Applications

• Multiple-port XAUI to SFI SFP+ line cards or NICs
• 10GBASE-KR-compliant backplane transceivers
• Synchronous Ethernet systems
• 10 GbE switch cards, router cards, and NICs

Procurement Notes

Verify the specific suffix 'XJU' against official Microchip documentation to confirm package type and temperature range. Confirm current lifecycle status as datasheets may reference older revisions. Ensure compatibility with required host interface standards before procurement.

Selection Notes

Select this component for high-density 10 Gbps platforms requiring low power consumption. Verify support for specific data rates such as 10.3 Gbps Ethernet or 10.5 Gbps Fibre Channel. Check interface requirements for MDIO or two-wire serial control. Evaluate EDC needs for SFP+ LRM or backplane applications.

Part Context

This part belongs to the VSC8488/VSC8484 family of multichannel 10 Gbps transceivers. These devices are designed to deliver minimum cost per channel with maximum port densities. They integrate world-class EDC performance across multiple data rates while maintaining low power dissipation.

Replacement Considerations

VSC8484YJP is a quad-channel variant within the same family offering similar EDC capabilities. Verify pinout and channel count differences when considering substitution. Consult official discontinuation notices for availability updates.
