88E1518-A0-NNB2C000

Product Overview

The 88E1518-A0-NNB2C000 from Marvell Semiconductor, Inc. is a surface-mount transceiver for Ethernet-oriented interface designs. It combines four drivers and four receivers in a 48-QFN (7 x 7) exposed-pad package and supports full and half duplex operation. The device operates at 10 Mbps, 100 Mbps, and 1 Gbps data rates while implementing IEEE 802.3 and IEEE 1588 protocols. Its 1.71 V to 1.89 V supply range and 0 °C to 70 °C (TA) operating temperature range define the electrical and environmental boundaries for board-level integration.

Key Features

• Transceiver type with 4 drivers and 4 receivers.
• Supports IEEE 802.3 and IEEE 1588 protocols.
• Operates at 10 Mbps, 100 Mbps, and 1 Gbps data rates.
• Supports full and half duplex operation.
• Surface-mount 48-QFN (7 x 7) package with exposed pad.
• Supply voltage range: 1.71 V to 1.89 V.
• Operating temperature range: 0 °C to 70 °C (TA).

Applications

• Network switch and router port designs requiring 10 Mbps, 100 Mbps, and 1 Gbps interface operation.
• Embedded Ethernet interface boards using IEEE 802.3 connectivity.
• Time synchronization systems that incorporate IEEE 1588 protocol support.

Design & Procurement Notes

Confirm that the selected 4/4 driver and receiver configuration, duplex mode, and 10 Mbps, 100 Mbps, and 1 Gbps data-rate support align with the intended Ethernet interface. The 1.71 V to 1.89 V supply and 0 °C to 70 °C (TA) range should be checked against the board power and ambient conditions. The 48-QFN (7 x 7) surface-mount package with exposed pad requires pad geometry and soldering process planning. IEEE 802.3 and IEEE 1588 protocol behavior should be verified in the final system, as protocol support does not specify higher-layer software or timing accuracy.
