MARVELL 88E2110-A0-BWS4I000 Gigabit Ethernet Transceiver: Datasheet and Technical Overview

The MARVELL 88E2110-A0-BWS4I000 is a highly integrated, single-port Gigabit Ethernet transceiver designed to provide a robust physical layer (PHY) solution for a wide range of networking applications. This device combines advanced mixed-signal processing with low-power architecture, making it a cornerstone component for enterprise switches, network interface cards, industrial systems, and embedded computing platforms.

Core Architecture and Key Features

Fabricated using an advanced process technology, the 88E2110 operates over a standard CAT 5e twisted-pair cable to deliver full wire-speed 10/100/1000 Mbps Ethernet connectivity. Its architecture is built around a sophisticated DSP core that ensures superior performance and signal integrity.

A critical feature of this transceiver is its compliance with the IEEE 802.3bz standard for 2.5G and 5G Base-T operation, providing forward compatibility and investment protection for next-generation network infrastructures. It supports both Energy Efficient Ethernet (EEE) as defined in IEEE 802.3az, significantly reducing power consumption during periods of low data activity, and IEEE 1588v2 Precision Time Protocol (PTP) for accurate clock synchronization, which is vital for time-sensitive applications in industrial automation and telecommunications.

The device integrates all necessary physical layer functions, including PMD sub-layers, PMA, and PCS, along with dual-speed (1.8V/3.3V) MAC interfaces for seamless connection to Ethernet switches or controllers. It also features advanced cable diagnostics, allowing for the precise identification of cable faults such as open circuits, short circuits, and impedance mismatches, which drastically reduces network downtime and maintenance costs.
