88E3018-A2-NNC1I000

Overview

The Marvell 88E3018-A2-NNC1I000 is a single-channel Fast Ethernet PHY transceiver supporting IEEE 802.3u standards for 10BASE-T and 100BASE-TX networks. It operates in full-duplex or half-duplex modes over twisted-pair cables and supports fiber-optic connections via 100BASE-FX. The device integrates RGMII and MII interfaces for MAC connectivity, featuring Virtual Cable Tester technology for cable diagnostics. Manufactured using a 0.15 μm CMOS process, it is housed in a 64-pin QFN package (9 mm x 9 mm) and includes JTAG boundary scan support.

Feature Summary

• Supports IEEE 802.3u Auto-Negotiation for automatic speed and duplex selection between 10BASE-T and 100BASE-TX.
• Integrates Marvell Virtual Cable Tester technology to remotely analyze attached cable plant quality and characteristics.
• Provides pin-upgradeable path toward future Gigabit Ethernet designs within the same physical footprint.
• Includes Far-End Fault Indication mechanism for transferring remote fault information in 100BASE-FX mode.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the A2 revision matches the design requirements. Check for RoHS compliance status if industrial grade certification is required for the target application environment.

Selection Notes

Select this component when a cost-effective Fast Ethernet solution with diagnostic capabilities is needed. The 64-pin QFN package allows for board space optimization compared to larger packages. Ensure the host system supports RGMII or MII interfaces. Consider the Industrial grade availability if operating temperatures exceed standard commercial limits.

Part Context

This device belongs to the fourth generation of Marvell DSP-based physical layer transceivers. It is part of the 88E301x family, which also includes the 88E3015. The 88E3018 offers additional features like JTAG support compared to the 88E3015, while maintaining compatibility with similar interface standards.

Replacement Considerations

The 88E3015 is a compatible alternative with fewer pins and no JTAG support. Verify pinout compatibility if substituting directly. No other public substitute part numbers are confirmed in the provided documentation.
