88E3083-C1-LKJ1C000

Overview

The Marvell 88E3083-C1-LKJ1C000 is an integrated 8-port 10/100BASE-T Fast Ethernet transceiver from the Alaska family. It operates at data rates of 10 Mb/s and 100 Mb/s, supporting full-duplex and half-duplex modes via IEEE 802.3u Auto-Negotiation. The device utilizes SMII and SSSMII interfaces to connect with Media Access Controllers. It features a 128-pin LQFP package and supports 100BASE-FX fiber on Port 7 only. Power consumption is rated at 150mW per port.

Feature Summary

• Integrates eight independent ports for high-density switch designs
• Includes Virtual Cable Tester technology for remote cable diagnostics
• Supports flexible serial and parallel LED configurations
• Provides Jumbo frame support up to 10 KB

Applications

• High-port density Fast Ethernet routers
• Fast Ethernet hubs
• Cost-effective Fast Ethernet switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product brief to ensure correct package type and feature set. Confirm interface compatibility with the target MAC controller before procurement. Check for any updated industrial grade availability or regional compliance requirements.

Selection Notes

Select this component when an 8-port Fast Ethernet solution with low power dissipation is required. Choose the 88E3083 over the 88E3082 if a smaller LQFP package is preferred and multi-fiber support is not needed. Ensure the design accommodates SMII or SSSMII signaling requirements.

Part Context

This part belongs to the Marvell Alaska 88E308x series of third-generation DSP-based Fast Ethernet transceivers. It shares core architectural features with the 88E3082 but differs in package size and fiber port availability. The series is designed for infrastructure applications requiring high port density.

Replacement Considerations

The 88E3082 is a functional alternative within the same family. Differences include the 88E3082's 224-pin TFBGA package versus the 88E3083's 128-pin LQFP, and the 88E3082's support for 100BASE-FX on all ports compared to the single port on the 88E3083.
