KSZ8873MLL/FLL/RLL

Integrated 3-Port 10/100 Managed

Switch with PHYs

Rev. 1.5

General Description

The KSZ8873MLL/FLL/RLL are highly integrated 3-port

switch on a chip ICs in the industry’s smallest 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 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.

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.

The device is available in RoHS-compliant 64-pin LQFP

package. Industrial-grade and Automotive-grade are

also available.

The datasheets and supporting documents can be found

at Micrel’s web site at: www.micrel.com.

KSZ8873MLL/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.
