88E1514-A0-NNP2C000

Overview

The Marvell 88E1514-A0-NNP2C000 is a single-port Gigabit Ethernet transceiver designed for commercial applications. It supports 10/100/1000BASE-T standards and utilizes SGMII to Copper or Copper to Fiber (1000BASE-X) operating modes. The device operates on a single 3.3V supply via an integrated switching voltage regulator, with I/O pads supporting 1.8V, 2.5V, or 3.3V LVCMOS standards. It features IEEE 802.3az-2010 Energy Efficient Ethernet (EEE), SyncE, PTP time stamping, and Advanced Virtual Cable Tester (VCT). The component is housed in a 56-pin QFN 8mm x 8mm Green package.

Feature Summary

• Supports SGMII to Copper and Copper to Fiber (1000BASE-X) interfaces
• Integrates MDI termination resistors and switching voltage regulators
• Includes Advanced Virtual Cable Tester (VCT) for remote cable diagnostics
• Compliant with IEEE 802.3az-2010 Energy Efficient Ethernet (EEE)

Applications

• Enterprise network switches
• Industrial routers
• Network gateways

Procurement Notes

Verify the specific ordering suffix against official Marvell documentation to confirm package type and temperature grade. Ensure compatibility with system power requirements, as the device requires a single 3.3V supply when utilizing internal regulators. Confirm that the design accommodates the 56-pin QFN footprint and thermal dissipation needs.

Selection Notes

Select this model specifically for designs requiring SGMII connectivity to copper media or fiber optics. Unlike other variants in the Alaska series, it does not support RGMII to Copper mode. Verify that the commercial temperature range meets application requirements, as industrial grades are available only in different part numbers within the same family.

Part Context

This component belongs to the Marvell Alaska 88E151x series of physical layer devices. It shares core PHY capabilities with the 88E1510, 88E1518, and 88E1512 but differs in interface support and packaging. The 88E1514 is distinctively configured for SGMII-based MAC connections rather than direct RGMII copper links.

Replacement Considerations

The 88E1512-A0-NNP2C000 serves as a functional substitute if the application requires RGMII to Copper support alongside SGMII options. Both share identical packages and EEE capabilities, though the 88E1512 offers broader interface flexibility.

FAQ

Does the 88E1514 support RGMII to Copper operation?

No, the 88E1514 does not support RGMII to Copper mode; it is limited to SGMII to Copper and Copper to Fiber configurations.

What power supply configuration is required?

The device can operate using a single 3.3V supply by utilizing its integrated switching voltage regulator to generate all necessary internal voltages.

How does the VCT feature function?

The Advanced Virtual Cable Tester uses Time Domain Reflectometry (TDR) technology to remotely identify cable malfunctions, such as opens, shorts, or impedance mismatches, reporting the distance to the fault.
