Interface - Controllers

The KSZ8794CNXIC-TR is a 4-port 10/100BASE-TX Ethernet switch designed for small-to-medium scale Local Area Network (LAN) applications. It is an excellent choice for creating and expanding your home, SOHO or small business networks. This device features a single-chip system-on-a-chip (SOC) architecture and provides flexible configurations for network applications. It features dual triple-speed transceivers, a built-in PHY, as well as a SPI interface.

Application Field

The KSZ8794CNXIC-TR Ethernet switch chip is used to increase the connectivity and performance of your wired Ethernet networks, while maintaining an easy-to-use, cost-effective solution. It is ideal for connecting 10/100 Ethernet RJ-45 ports using Cat5 UTP cables, and can be configured as either a shared cable or as a hubless switch. In either configuration, the chip can bring robust performance and low-cost, reliable connectivity to any network.

The chip also provides support for Quality of Service (QoS) capabilities such as VLAN segmentation, Wi-Fi prioritization, and port-based prioritization. This chip can also be configured to support several redundant Ethernet networks in a single system and provide high availability, making it a great switch for business-critical applications. The KSZ8794CNXIC-TR is also able to support both standard and extended features such as multicast and broadcast, allowing for much more efficient communication and more reliable data transmission.

Working Principle

The KSZ8794CNXIC-TR Ethernet switch is based on an architecture that uses a system-on-a-chip (SOC) design. This architecture provides a simple, highly integrated solution that is open to future development and enhancement. The device contains both programmable logic and embedded hardware that works together to provide a low-cost, energy-efficient solution. The SOC design consists of a single-chip system-on-a-chip that contains two triple-speed transceivers, a built-in PHY, a 2KB packet buffer, and a SPI interface.

This architecture uses a technique called carrier sense multiple access with collision detection (CSMA/CD) to facilitate communication between devices. This Ethernet switch chip integrates a self-learning store-and-forward switching fabric which supports four ports for 10/100BASE-TX Ethernet over twisted pair cables. This switching fabric can detect, route, and forward packets from the MAC address to their destination at full-duplex operation. It also supports jumbo frames and has a filtering database for incoming traffic.

The chip also provides many configuration options to enable flexibility of applications. These options include port auto-sensing, port-level Quality of Service (QoS), VLAN segmentation and user-defined traffic flow control. Other options include broadcast and multicast support, port-based prioritization and reliable packet transmission. All of these features provide for smooth, secure and efficient data transfer.

Conclusion

The KSZ8794CNXIC-TR Ethernet switch is an excellent choice for home, SOHO and small business networks. It provides high-performance, reliable and cost-effective Ethernet connectivity. The SOC architecture ensures that the device is future-proof, upgradeable and integrates easily with other Ethernet networks. Furthermore, the chip provides extensive support for Quality of Service (QoS) features and VLAN segmentation, as well as multiple redundancy options for business-critical applications.
