Introduction to KSZ8864RMNUB

KSZ8864RMNUB is a single-chip, high-speed, low-power WAN switch designed by Micrel, Inc. Using RJ-45 ports with an Ethernet, it allows for the switching of four 10/100Mbps LAN ports on different networks. It is an optimized switch solution for high-volume networking applications.

Features and Capabilities of KSZ8864RMNUB

The main features of the KSZ8864RMNUB are its low power consumption, low latency, single chip integration, and wide operating temperature range. The KSZ8864RMNUB supports full-duplex and automatic flow control. It has IEEE 802.3x and IEEE 802.3z compliant Ethernet interfaces and supports both 10BASE-T and 100BASE-TX networks. On the network side, the device provides two-port switching between 10BASE-T and 100BASE-TX networks. The switch also supports port-based rate limiting and provides a maximum throughput of 10-Mbps or up to 100-Mbps depending on the configuration.The switch supports a wide range of operating temperatures from -40 degrees to 85 degrees Celsius. It also supports a variety of Power over Ethernet (PoE).

Application Field and Working Principle of KSZ8864RMNUB

The KSZ8864RMNUB is designed for a variety of applications such as network switches and wireless access points, as well as various Ethernet-based industrial and consumer applications.The KSZ8864RMNUB uses a non-blocking packet switching architecture to forward data between LAN ports. A 64-Kb on-chip buffer helps to ensure that packets are delivered reliably and quickly. The switch also performs IEEE 802.1p, QoS, VLAN and multicast frame filtering, as well as rate limiting and broadcast storm protection features.The device works by sniffing, buffering and forwarding Ethernet frames that contain network-level information. The VLAN ID and port level information is applied to packet headers to enable different types of traffic to be serviced on different parts of the network. Additionally, the switch supports line-rate traffic with minimal latency and jitter, allowing for greater reliability and performance.

Conclusion

The KSZ8864RMNUB is an advanced, low-power single-chip WAN switch, optimized for a variety of networking applications. It supports 10/100 Mbps switching between different networks, low latency and comprehensive IEEE 802.1p capability. It also provides a power efficient design and is capable of operating over a wide temperature range. The device provides a flexible feature set and highly secure performance.
