KSZ8463ML/RL/FML/FRL
IEEE 1588 Precision Time ProtocolEnabled, Three-Port, 10/100-Managed
Switch with MII or RMII
Revision 1.0 General Description
The KSZ8463 ETHERSYNCHв„ў product line consists of
IEEE 1588v2 enabled Ethernet switches, providing
integrated communications and synchronization for a
range of Industrial Ethernet applications.
The KSZ8463 ETHERSYNCH product line enables
distributed, daisy-chained topologies preferred for
Industrial Ethernet networks. Conventional centralized
(i.e., star-wired) topologies are also supported for dualhomed, fault-tolerant arrangements.
A flexible set of standard MAC interfaces is provided to
interface to external host processors with embedded
Ethernet MACs: KSZ8463ML: Media Independent Interface (MII) KSZ8463RL: Reduced Media Independent Interface
(RMII) KSZ8463FML: MII, supports 100BASE-FX fiber in
addition to 10/100BASE-TX copper KSZ8463FRL: RMII, supports 100BASE-FX fiber in
addition to 10/100BASE-TX copper
The KSZ8463 devices incorporate the IEEE 1588v2
protocol. Sub-microsecond synchronization is available via
the use of hardware-based time-stamping and transparent
clocks making it the ideal solution for time synchronized
Layer 2 communication in critical industrial applications. ETHERSYNCHв„ў …
