KSZ8873RLLI

MICREL SEMICONDUCTOR KSZ8873RLLI Ethernet Controller, 100Mbps, IEEE 802.3, IEEE 802.3u, 2.375V, 3.465V, LQFP, 64Pins

The is a 3-port highly integrated 10/100 Managed Switch in a smallest footprint. It is designed to enable a new generation of low port count, cost-sensitive and power efficient 10/100Mbps switch systems. Low power consumption, advanced power management and sophisticated QoS features e.g., IPv6 priority classification support make thus device ideal. The KSZ8873 family is designed to support the GREEN requirement in today"s switch systems. Advanced power management schemes include hardware power down, software power down, per port power down and the energy detect mode that shuts downs the transceiver when a port is idle. It offers a by-pass mode, which enables system-level power saving. In this mode, the processor connected to the switch through the MII interface can be shut down without impacting the normal switch operation.
