Microchip | KSZ8873RLL

Micrel Inc., is a leading manufacturer of IC solutions for the worldwide analog, Ethernet and high bandwidth markets. The Company's products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high-speed communication, clock management, Ethernet switch and physical layer transceiver integrated circuits. These products address a wide range of rapidly growing end markets including cellular handsets, portable and enterprise computing, enterprise and home networking, wide area and metropolitan area networks and industrial equipment.

Micrel acquired Kendin Communications in June of 2001. The Ethernet product line has continued to evolve and grow with the market. Micrel's Controllers are known for robust performance, interoperability and low power.

The KSZ8873RLL is a highly integrated 3-port switch on a chip ICs in the industry's smallest footprint. It is designed to enable a new generation of low port count, cost-sensitve and power-efficient 10/100Mbps switch systems.  Low power consumption, advanced power management, and sophisticated QoS features (e.g.  IPv6 priority classification support) make this device ideal for IPTV, IP-STB, VoIP, and automotive and industrial applications.

The KSZ8873 family is designed to support the GREEN requirement in today's switch systems. Advanced power management schemes include hardware and power down, software power down, and the energy detect mode that shuts down the transceiver when a port is idle.

The KSZ8873RLL also offers the by-pass mode, which enables system-level power savings.  In this mode, the processor connected to the switch through the MII interface can be shut down without impacting the normal operation. 

The KSZ8873RLL features two 10/100BASE-T/TX transceivers and one RMII interface. This device is ROHS compliant and comes in a 64-pin LQFP package.
