KSZ8462HL/KSZ8462FHL
IEEE 1588 Precision Time Protocol-Enabled
Two-Port 10/100Mb/s Ethernet Switch
with 8 or 16 Bit Host Interface
Revision 1.0 General Description
The KSZ8462 ETHERSYNCHв„ў product line consists of
IEEE 1588v2-enabled Ethernet switches, providing
integrated communications and synchronization for a
range of industrial Ethernet applications.
The KSZ8462 ETHERSYNCH product enables distributed,
daisy-chained topologies preferred for Industrial Ethernet
networks. Conventional centralized (i.e., star-wired)
topologies are also supported for dual-homed, fault
tolerant arrangements.
A flexible 8-or 16-bit general bus interface is provided for
interfacing to an external host processor.
The KSZ8462 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
The KSZ8462 product is built upon Micrel’s
industry-leading Ethernet technology, with features …
