KSZ8873FLL [Microchip]

The KSZ8873MML/MLL/FLL/RLL are highly integrated 3-port switch on a chip ICs in a small footprint. They are 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 these devices ideal for IPTV, IP-STB, VoIP, 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 power down, software power down, per port power down and the energy detect mode that shuts downs the transceiver when a port is idle.

KSZ8873MML/MLL/FLL/RLL also offer a by-pass mode. In this mode, the processor connected to the switch through the MII interface can be shut down without impacting the normal switch operation.

The configurations provided by the KSZ8873 family enables the flexibility to meet requirements of different applications:

• KSZ8873MLL - Two 10/100BASE-T/TX transceivers and one MII interface 

• KSZ8873RLL - Two 10/100BASE-T/TX transceivers and one RMII interface 

• KSZ8873FLL - Two 100BASE-FX transceivers and one MII interface 

• KSZ8873MML - Two MII interfaces and one 10/100BASE-T/TX transceivers

The device is available in RoHS-compliant 64-pin LQFP package. Industrial-grade and Automotive-grade are also available.
