88E3018-A2-NNC1C000

Overview

The Marvell 88E3018-A2-NNC1C000 is a single-channel Fast Ethernet PHY transceiver supporting IEEE 802.3u standards for 10BASE-T and 100BASE-TX networks over twisted-pair cabling. It operates in full-duplex or half-duplex modes with automatic speed and duplex selection via Auto-Negotiation. The device integrates RGMII and MII interfaces for MAC connectivity, alongside a PECL interface for 100BASE-FX fiber applications. Key features include Virtual Cable Tester technology for remote cable diagnostics, Far-End Fault Indication, and JTAG boundary scan support. Manufactured using a 0.15 μm CMOS process, it utilizes advanced DSP techniques to minimize power dissipation while maintaining high performance.

Feature Summary

• Supports IEEE 802.3 compliant 10BASE-T and 100BASE-TX ports with automatic MDI/MDIX crossover
• Integrates Virtual Cable Tester technology for remote analysis of attached cable plant quality
• Includes JTAG Standard Test Access Port and Boundary Scan capabilities for manufacturing testing
• Provides flexible serial management interface (MDC/MDIO) for register access and programmable interrupts

Applications

• Enterprise network infrastructure equipment
• Industrial automation control systems
• Telecommunications access nodes
• Datacom networking switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the component meets all required environmental compliance standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a pin-upgradeable path to Gigabit Ethernet designs is required within a Fast Ethernet application. Ensure the design accommodates the 64-pin QFN package dimensions and supports the necessary voltage regulators for AVDD and DVDD supplies as specified in the electrical characteristics section.

Part Context

This part belongs to the fourth-generation Marvell DSP-based physical layer transceiver family designed specifically for Fast Ethernet applications. It shares functional similarities with the 88E3015 but offers an expanded pin count to support additional features like JTAG boundary scan and industrial-grade operation options.

Replacement Considerations

The 88E3015 serves as a compatible alternative for designs not requiring JTAG support, offering a cost-efficient option in a smaller 56-pin QFN package. Verify pin compatibility and feature requirements before substituting.
