BCM82328B1KFSBG is an integrated device used in many types of microelectronic circuits and systems. It is a high-performance, multi-channel network processor that combines the hardware necessary for a full duplex Ethernet interface, such as an energy-efficient clocking, packet-level filtering, network-level QoS, flow control, congestion control, and support for multiple network interface types. It is intended to be used in applications such as Gigabit Ethernet switches, Ethernet adapters, DSL modems, and long-haul wide-area network transport.

The BCM82328B1KFSBG operates with a single clock. It supports both the IEEE 802.3 and the IEEE 802.3x standards, and provides a variety of physical layer interface options, including 10/100/1000Base-T, 10Base-F, and T1/E1. It also provides a full-featured media access controller and frame engine, allowing the device to handle up to four single-channel Gigabit Ethernet ports. The device can be configured with 4 GbE ports, two 10/100/1000Base-T and two 10Base-F ports, or two GbE ports, and two T1/E1 ports.

The working principle of the BCM82328B1KFSBG is based on a comprehensive packet-level filtering and scheduling system. The filtering and scheduling system is designed to provide flexible scheduling of packets to ensure QoS for all flows. The system supports both ingress and egress port-level priority scheduling, packet-level classification, and packet processing capabilities, providing an efficient and low-latency path for packet forwarding.

The BCM82328B1KFSBG also supports advanced features such as forwarding and shaping. The forwarding feature allows the device to automatically select the best path for a given data packet, enabling efficient packet forwarding and traffic management. The shaping feature allows the device to regulate the speed of packet-sending to help reduce network congestion. This ensures that a given flow is always limited to the specified rate, preventing excessive bandwidth utilisation.

In addition, the BCM82328B1KFSBG supports advanced security features such as denial-of-service (DoS) protection, multicast snooping, and packet filtering. These features enable the device to maintain a robust and secure network, helping to protect against malicious attacks and malicious traffic.

In summary, the BCM82328B1KFSBG is a versatile and powerful integrated device used in many types of microelectronic circuits and systems. It is able to provide a high-performance, multi-channel network processor with support for multiple network interface types. It uses a comprehensive packet-level filtering and scheduling system to provide flexible scheduling of packets to ensure QoS for all flows. In addition, the device supports advanced features such as forwarding and shaping to regulate the speed of packet sending and advanced security features such as DoS protection, multicast snooping, and packet filtering to maintain a robust and secure network.
