MARVELL 98DX4122C0-BIH2C000 Gigabit Ethernet Switch Controller Datasheet Overview

The MARVELL 98DX4122C0-BIH2C000 is a highly integrated, high-performance Gigabit Ethernet switch controller designed for enterprise, data center, and carrier-grade networking applications. This advanced system-on-chip (SoC) delivers robust switching capabilities, combining high port density with low power consumption and advanced feature sets to meet the demanding requirements of modern network infrastructures.

A core strength of this controller is its high level of integration. It incorporates multiple Gigabit Ethernet PHYs, a high-speed switching fabric, and sophisticated management interfaces into a single chip. This integration significantly reduces the bill of materials (BOM) and board space, simplifying design and accelerating time-to-market for network equipment manufacturers.

The device supports a comprehensive set of Layer 2 and Layer 3 switching features, including advanced Quality of Service (QoS), security access control lists (ACLs), and extensive traffic management capabilities. These features ensure reliable, deterministic, and secure data transmission, which is critical for business-critical applications and services.

Furthermore, the 98DX4122C0 is engineered for resiliency and high availability, supporting protocols such as Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP). Its support for hardware-based virtualization technologies allows for the creation of secure, isolated network segments within a single physical infrastructure.

Target applications for this powerful controller include next-generation top-of-rack (ToR) switches, network interface cards (NICs), smart network interface cards (SmartNICs), and various embedded networking platforms. Its combination of performance, integration, and advanced feature set makes it a pivotal component in building scalable and efficient network architectures.

ICGOODFIND: The Marvell 98DX4122C0-BIH2C000 stands out as a highly integrated and feature-rich solution, offering exceptional performance and flexibility for designing advanced networking equipment.
