KSZ8863MLL/FLL/RLL
Integrated 3-Port 10/100 Managed
Switch with PHYs
Revision 1.5
General Description
The KSZ8863MLL/FLL/RLL 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 KSZ8863 family is designed to support the GREEN
requirement in today’s switch systems. Advanced power
management schemes include software power down,
per port power down and the energy detect mode that
shuts downs the transceiver when a port is idle.
The configurations provided by the KSZ8863 family
enables the flexibility to meet requirements of different
applications:
• KSZ8863MLL: Two 10/100BASE-T/TX transceivers
and one MII interface.
• KSZ8863RLL: Two 10/100BASE-T/TX transceivers
and one RMII interface.
• KSZ8863FLL: One 100BASE-FX, one 10/100BASE-
T/TX transceivers and one MII interface.
The device is available in RoHS-compliant 48-pin LQFP
package. Industrial-grade and Automotive-grade are
also available.
KSZ8863MLL/FLL/RLL 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.
