Rev. 1.6 General Description
The KSZ8873MML are highly integrated 3-port switch on
a chip ICs in industry’s smallest footprint. It is designed
to enable a new generation of low port count, costsensitive 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 also offer 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.
The configurations provided by the KSZ8873 family
enables the flexibility to meet requirements of different …
