88E1543-A1-LKJ2C000

Overview

The Marvell 88E1543-A1-LKJ2C000 is a quad-port Gigabit Ethernet transceiver supporting 10BASE-T, 100BASE-TX, and 1000BASE-T standards. It features four independent transceivers with Quad Serial Gigabit Media Independent Interface (SGMII) connectivity. The device integrates an internal switching voltage regulator for single 3.3V operation and includes MDI interface termination resistors. Operating within a temperature range of 0°C to +70°C, it utilizes advanced mixed-signal processing for equalization and error correction at gigabit data rates.

Feature Summary

• Supports Energy Efficient Ethernet (IEEE 802.3az) with legacy MAC compatibility via EEE buffering
• Integrates Virtual Cable Tester technology for remote cable fault detection
• Features integrated switching voltage regulator enabling single 3.3V supply operation
• Includes built-in MDI interface termination resistors to simplify board layout

Applications

• Enterprise standalone and switching systems
• Embedded network equipment
• Consumer networking devices
• Metro and service provider infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a quad-port Gigabit PHY with SGMII system interface is required. It is suitable for designs needing integrated voltage regulation and reduced external component count. Consider the 128-pin LQFP package constraints and thermal dissipation capabilities for the specific enclosure design.

Part Context

This part belongs to the Marvell Alaska family of Gigabit Ethernet transceivers. The Alaska series provides physical layer solutions for enterprise, embedded, consumer, and carrier applications. The 88E154x series specifically focuses on multi-port configurations with integrated power management features.

Replacement Considerations

Check the 88E1548-A1-BAM2C000 for similar quad-port functionality in a TFBGA-196 package with QSGMII support. Verify pinout compatibility and software register mapping before substituting.
