The KSZ8873MLL is an integrated managed five-port Ethernet Switch with two 100BASE-TX PHYs and three MII/RMII ports. It allows communication between separate networks, connects up to five Ethernet devices and ensures they can exchange data.

Application Field

The KSZ8873MLL is a highly integrated switch designed to provide an efficient and cost-effective way to bridge multiple networks together. It is typically used in applications such as industrial automation networks, factory floor control, network bridging, and medical instrumentation. It is ideal for use in embedded designs such as switches, routers, cameras, and security systems. With low-power consumption and a high integration level, the KSZ8873MLL is suitable for both embedded and standalone applications.

Working Principle

The KSZ8873MLL is based on a completely integrated Layer 2 switching solution that can operate in both the store-and-forward and cut-through switching modes. The internal non-blocking switch fabric allows for full bandwidth on each port for data transmission. The integrated four-port Fast Ethernet (FE) Switch includes two MII/RMII ports and two 100BASE-TX physical layer (PHY) ports. It also includes an embedded Media Access Control (MAC) and buffering system that supports multiple packet/frame forwarding/filtering applications.

For advanced operations, the KSZ8873MLL consists of an array of traffic management and queuing functions such as four-level of priority queues, automatic queue switching, VLAN support, IPv4/IPv6 packet filtering, and rate control. The integrated 10/100Mbps PHYs can detect and configure the speed and duplex of communication. For enhanced network security, the KSZ8873MLL features proprietary Security Mode layers including Data Encapsulation, Encryption, and Content Guidelines Support. With integrated support for Wake on LAN (WoL), it helps conserve power in remote applications and sleep modes.

In addition to these features, the KSZ8873MLL provides enhanced performance and system reliability with its advanced auto-negotiation, cable diagnostics, loop detection support, power management, and process ID control. It is designed to ensure optimum performance by monitoring and controlling network traffic, reducing jitter and latency. The advanced system design of the KSZ8873MLL also enables it to be used for both mobile and low-power applications.
