|Micrel, Inc.'s KSZ9021RN is a single-port 10/100/1000 Base-T Gigabit transceiver in industry's smallest footprint, supporting data transfer over standard CAT-5 unshielded twisted pair cable. This device offers robust performance and low power consumption. On-chip integration of termination resistors and the LDO controller, along with built-in diagnostic features, significantly reduces the cost and the complexity of Gigabit Ethernet applications. This device is ideal for enabling Gigabit Ethernet performance in SOHO and SMB networking applications such as SOHO media center, wired/wireless Gigabit SOHO/SMB router, and VolP gateway. The KSZ9021GN provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet processors and switches for data transfer at 1000 Mbps speed. The device is available in a RoHS-compliant 48-pin QFN package. Industrial grade is also available.
