MARVELL 88E3083-C1-LKJ1C000 Ethernet Switch Controller Datasheet and Technical Overview

The MARVELL 88E3083-C1-LKJ1C000 is a highly integrated, low-power, and high-performance 8-port Gigabit Ethernet switch controller designed for a wide range of enterprise, industrial, and embedded networking applications. Manufactured by Marvell, a leader in semiconductor solutions, this controller combines advanced Layer 2 management features with robust hardware capabilities to deliver reliable and efficient network switching.

Key Features and Architecture

At the heart of the 88E3083 is a powerful switching engine that supports non-blocking wire-speed performance on all ports. The device integrates eight 10/100/1000 Mbps Ethernet PHYs, along with a SERDES interface for additional flexibility in connecting to fiber transceivers or other controllers. Its built-in MAC (Media Access Control) units and a high-speed switch fabric ensure minimal latency and maximum data throughput, making it suitable for bandwidth-intensive tasks.

A standout feature is its comprehensive Quality of Service (QoS) support. The controller employs advanced traffic classification and prioritization mechanisms, including IEEE 802.1p-based priority levels and DiffServ (Differentiated Services). This allows network administrators to guarantee bandwidth for critical applications, such as VoIP or video streaming, ensuring a seamless user experience.

For enhanced network security, the 88E3083 offers IEEE 802.1X port-based authentication and robust Access Control List (ACL) capabilities. These features enable secure network access and prevent unauthorized devices from connecting to the network. Additionally, the controller supports VLAN (Virtual Local Area Network) tagging (IEEE 802.1Q), which helps in segmenting network traffic for improved security and management.

Management and Control

The device can be managed through a Standard Management Interface (SMI) via its Serial Management Interface (SMI) clause 22/45. It provides access to a rich set of Management Information Bases (MIBs), allowing for detailed monitoring of network statistics like packet counters, error rates, and traffic flows. This is crucial for network diagnostics and performance optimization.

Energy Efficiency

Reflecting modern environmental concerns, the 88E3083 incorporates Marvell's Energy Efficient Ethernet (EEE) technology. This feature, compliant with the IEEE 802.3az standard, significantly reduces power consumption during periods of low data activity, making it an ideal choice for green initiatives and power-sensitive applications.

Target Applications

Its combination of high integration, management features, and low power consumption makes the 88E3083-C1-LKJ1C000 perfect for:

Managed Network Switches: For small to medium-sized businesses requiring control and visibility.
