BCM5320MKPBG Datasheet: Features and Technical Specifications

The BCM5320MKPBG is a highly integrated, low-power, single-chip 8-port Gigabit Ethernet switch solution developed by Broadcom (now part of Avago Technologies). It is designed for use in enterprise-grade networking equipment, network-attached storage (NAS) systems, and small to medium business (SMB) switches, providing robust performance and advanced management features.

Key Features

The BCM5320MKPBG stands out with its comprehensive integration and feature set:

High Level of Integration: The device integrates eight 10/100/1000 Mbps Ethernet transceivers, a high-performance non-blocking switch fabric, MAC controllers, buffer memory, and a management interface into a single monolithic chip. This significantly reduces the bill of materials and board space requirements.

Non-Blocking Switch Fabric: The architecture delivers a full wire-speed switching performance on all ports simultaneously, supporting up to 16 Gbps of aggregate bandwidth without any packet loss under full load.

Advanced Management Capabilities: It supports comprehensive Quality of Service (QoS) features, including four priority queues per port, strict priority and weighted round-robin (WRR) scheduling, and IEEE 802.1p packet prioritization. It also includes IGMP snooping for efficient multicast traffic management and Jumbo Frame support (up to 9KB frames) to improve large data transfer efficiency.

VLAN Support: The switch supports IEEE 802.1Q VLANs with port-based and protocol-based VLAN configurations, enabling secure and efficient network segmentation.

Energy Efficiency: Incorporates advanced power-saving features such as Automagic® Power-Down, which reduces power consumption by automatically powering down unused ports and adjusting power usage based on cable length.
