88E1512-A0-NNP2I000

Overview

The Marvell 88E1512-A0-NNP2I000 is an industrial-grade, single-port Gigabit Ethernet transceiver designed for the Alaska family. It implements 10/100/1000BASE-T standards over standard CAT5 unshielded twisted pair cabling. The device supports RGMII and SGMII MAC interfaces, enabling flexible connectivity to switches or fiber modules via SFP. Key electrical parameters include a maximum data rate of 1 Gb/s, operating voltage range of 950 mV to 1.05 V for core logic, and a supply current maximum of 72 mA. It operates within an extended temperature range from -40°C to +85°C and is housed in a 56-pin QFN package.

Feature Summary

• Supports IEEE 802.3az Energy Efficient Ethernet (EEE) with buffering for legacy MAC compatibility
• Integrates MDI termination resistors to eliminate external passive components
• Includes Advanced Virtual Cable Tester (VCT) using Time Domain Reflectometry for fault detection
• Features integrated switching voltage regulators allowing operation from a single 3.3V supply

Applications

• Industrial Ethernet switches and routers
• Fiber optic media converters utilizing SGMII to Copper modes
• Network Attached Storage (NAS) systems requiring low power dissipation
• Automotive infotainment and gateway applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact package type, temperature grade, and I/O voltage requirements. Ensure that the procurement documentation matches the required Industrial temperature rating (-40°C to +85°C). Cross-reference the component marking with official Marvell identification codes to prevent counterfeit substitution.

Selection Notes

Select this component when an industrial temperature range is mandatory for the deployment environment. The 88E1512 variant specifically enables SGMII-to-Copper and RGMII-to-Fiber configurations, distinguishing it from the 88E1510 which lacks these serial interface capabilities. Confirm that the system design accommodates the 56-pin QFN footprint and thermal dissipation requirements associated with the internal switching regulator.

Part Context

This component belongs to the Marvell Alaska 88E151x series, which includes the 88E1510, 88E1512, 88E1514, and 88E1518 models. The 88E1512 is distinguished by its support for both RGMII and SGMII interfaces, whereas the 88E1510 is limited to RGMII. The 'I' suffix in the part number denotes the Industrial temperature classification, differentiating it from Commercial grade variants like the 88E1512-A0-NNP2C000.

Replacement Considerations

The 88E1510-A0-NNP2I000 serves as a functional substitute if SGMII connectivity is not required. For commercial applications, the 88E1512-A0-NNP2C000 offers identical electrical performance but lacks the extended temperature range.
