Product Brief
Integrated 10/100BASE-T/TX/FX 3-Port Switch
Description
The KSZ8873MLL, KSZ8873RLL, KSZ8873FLL, and
KSZ8873MML are highly integrated 3-port switch on a chip
ICs in 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 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, and the energy detect mode that
shuts downs the transceiver when a port is idle.
KSZ8873MLL, KSZ8873RLL, and KSZ8873FLL also offer
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 switch operation.
The configurations provided by the KSZ8873 family enable
the flexibility to meet requirements of different applications:
• KSZ8873MLL: Two 10/100BASE-T/TX transceivers
and one MII interface.
• KSZ8873MML: One 10/100BASE-T/TX transceiver
and two MII interfaces.
• KSZ8873RLL: Two 10/100BASE-T/TX transceivers
and one RMII interface.
• KSZ8873FLL: Two 10/100BASE-FX transceivers and
one MII interface.
The devices are available in RoHS-compliant 64-pin LQFP
package. Industrial grade is also available.
