88E3082-C1-BAR1C000

Overview

The Marvell 88E3082-C1-BAR1C000 is an integrated eight-port 10/100BASE-T Fast Ethernet transceiver based on third-generation DSP technology. It operates within a power supply range of 1.14 V to 1.26 V and supports data rates of 10 Mb/s and 100 Mb/s. The device accommodates full-duplex and half-duplex modes with MII, RGMII, RMII, SMII, and SSSMII interfaces. It functions reliably in temperatures from 0°C to +70°C and utilizes a 224-pin TFBGA package.

Feature Summary

• Ultra-low power dissipation at 150mW per port for high-density switch designs
• Integrated Virtual Cable Tester (VCT) for remote cable diagnostics
• Supports IEEE 802.3u Auto-Negotiation for automatic speed and duplex selection
• Flexible interface options including RMII, SMII, and SSSMII to reduce I/O pin counts

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 official documentation to confirm exact package type, temperature grade, and lead time requirements. Ensure compatibility with system voltage levels and interface standards before procurement. Cross-reference the component marking with the datasheet to prevent counterfeit substitution during acquisition.

Selection Notes

Select this component when designing systems requiring eight independent 10/100BASE-T ports with minimal power consumption. Consider the 224-pin TFBGA package constraints and verify that the host MAC supports the required digital interfaces such as RMII or SSSMII. Evaluate thermal management needs given the low per-port power dissipation characteristics.

Part Context

This part belongs to the Marvell Alaska 88E308x family of Fast Ethernet transceivers. It shares core architectural features with the 88E3083 but differs in package size and fiber support capabilities. The series is designed to provide industry-leading power efficiency and advanced diagnostic features for embedded networking applications.

Replacement Considerations

The 88E3083 serves as a functional alternative within the same product family. Verify interface compatibility, specifically regarding RMII support which is exclusive to the 88E3082. Check package footprint differences between the 224-pin TFBGA and 128-pin LQFP to ensure mechanical fit.
