MARVELL 88E6393XA0-BXB2C000: A High-Performance Gigabit Ethernet Switch Solution

The MARVELL 88E6393XA0-BXB2C000 represents a sophisticated and highly integrated Gigabit Ethernet switch chip designed to meet the demanding requirements of modern enterprise, industrial, and carrier-grade networking equipment. This 11-port device is engineered to deliver robust performance, advanced security features, and flexible configuration options, making it a cornerstone for next-generation network infrastructure.

Technical Specifications and Core Architecture

At its heart, the 88E6393X is a member of Marvell's Prestera® family of switches. It is built on a mature and high-performance architecture that supports a rich set of Layer 2 and Layer 3 features. The chip typically integrates eleven Gigabit Ethernet ports, with a high degree of flexibility in their configuration. These ports can be a mix of 10/100/1000BASE-T copper interfaces and 1000BASE-X SGMII fiber interfaces, often supported through Marvell's innovative programmable SerDes technology, allowing designers to tailor the physical layer connectivity to their specific application needs.

A key feature of this switch is its non-blocking switch fabric, which ensures wire-speed performance on all ports simultaneously, providing an aggregate bandwidth of up to 22 Gbps. This is crucial for preventing bottlenecks in high-traffic environments. The device supports a large address table with up to 16K MAC addresses, ensuring efficient forwarding in large, complex networks.

Advanced Feature Set

The 88E6393X is far more than a simple switch; it is a fully managed solution offering comprehensive features:

Quality of Service (QoS): It provides advanced traffic management with eight priority queues per port and supports strict priority and weighted round-robin (WRR) scheduling algorithms. This allows for precise prioritization of latency-sensitive traffic like voice and video.

Security: The switch includes robust security functionalities such as IEEE 802.1X port-based authentication, Access Control Lists (ACLs) for filtering traffic based on L2-L4 parameters, and secure management interfaces.

Resiliency: It offers comprehensive support for network redundancy protocols including Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP), and Ethernet Ring Protection Switching (ERPS), ensuring high network availability.

Virtualization: Support for IEEE 802.1Q VLAN is standard, enabling network segmentation for security and traffic management. It also supports Layer 3 static routing and Routing Information Protocol (RIP) for basic inter-VLAN routing.

Management: The device can be managed through a variety of interfaces, including a standard SMI/MDIO interface, SPI, and I2C, offering flexibility for different system designs.

Target Applications

The versatility and power of the 88E6393X make it suitable for a wide array of applications, including:

Enterprise and Campus Network Switches

Industrial Ethernet Switches (operating over extended temperature ranges)

Carrier Ethernet Access Devices

Network Interface Cards (NICs) and Network Appliances

ICGOODFIND: The Marvell 88E6393XA0-BXB2C000 stands out as a highly capable and flexible managed Gigabit Ethernet switch chip. Its blend of high port density, wire-speed performance, advanced management features, and robust security suite makes it an ideal solution for building reliable, scalable, and high-performance networking infrastructure across enterprise, industrial, and service provider markets.
