The KSZ9021GN is the ideal choice for designers who are seeking a highly integrated, small-footprint, low-power solution for 10/100 Base-T or 100 Base-Tx applications. It has integrated auto-negotiated Ethernet protocol support and helps enable faster time-to-market and simpler design. The KSZ9021GN features built-in MII/RMII/RGMII/SMII/XGMII interfaces and operates with a wide range of supply voltage (from 1.6V to 3.3V). It also has an integrated energy efficient interconnect, allowing it to connect to an external PHY with minimal impact on overall board area and power consumption. The KSZ9021GN transceiver is a single-port Gigabit transceiver with three operating modes: 10/100 Mbps, 1000 Mbps, and 10/100/1000 Mbps. The transceiver supports full-duplex operation and features full-set auto-negotiate capabilities. In the 10/100 Mbps operation, the KSZ9021GN can be used as a 10/100 Mbps transceiver or 100 Mbps receiver. The 10/100 Mbps operation is compatible with the IEEE 802.3 standard and provides complete compatibility between 10/100 Mbps network nodes.In the 1000 Mbps operating mode, the KSZ9021GN can be used as a 1000 Mbps transceiver or receiver. It is compliant to the IEEE 802.3ab standard. It is also fully backward compatible with 10/100Base-TX networks. The 10/100/1000 Mbps operation enables multiple interfaces with the same device to be used for simultaneous communication with other network nodes. The KSZ9021GN transceiver is designed to offer low power consumption. It supports energy efficient Ethernet (EEE) and advanced power management (PME) for minimal power consumption. The transceiver also has built-in voltage-mode logic (VML) for improved performance and lower latency when compared to edge- and level-triggered logic. The KSZ9021GN also features integrated memory management and error correction support, ensuring reliable data transfer. The transceiver incorporates advanced packet and link control functions to handle network traffic more efficiently. It also supports an integrated thermal sensor that monitors the junction temperature and can be used to reduce power consumption when necessary. In summary, the KSZ9021GN is a high-performance transceiver that provides a cost-effective, versatile and reliable solution for 10/100 Base-T and 100 Base-TX networks. Through intelligent design and efficient design, it can help reduce power consumption while maintaining performance and reliability. With its integrated auto-negotiated Ethernet protocol support, the KSZ9021GN can help enable faster time-to-market and simpler design.
