Enabled, Three-Port, 10/100-Managed
Switch with MII or RMII
Revision 1.0
General Description
The KSZ8463 ETHERSYNCH™ 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 dual-
homed, 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.
Extensive general purpose I/O (GPIO) capabilities are
available to use with the IEEE 1588v2 PTP to efficiently
and accurately interface to locally connected devices.
Complementing the industry’s most-integrated IEEE
1588v2 device is a precision timing protocol (PTP) v2
software stack that has been pre-qualified with the
KSZ84xx product family. The PTP stack has been
optimized around the KSZ84xx chip architecture, and is
available in source code format along with Micrel’s chip
driver.
ETHERSYNCH™
The KSZ8463 product line is built upon Micrel’s industry-
leading Ethernet technology, with features designed to
offload host processing and streamline your overall design.
• Wire-speed Ethernet switching fabric with extensive
filtering
• Two integrated 10/100BASE-TX PHY transceivers,
featuring the industry’s lowest power consumption
• Full-featured quality-of-service (QoS) support
• Flexible management options that support common
standard interfaces
The wire-speed, store-and-forward switching fabric
provides a full complement of QoS and congestion control
features optimized for real-time Ethernet.
A robust assortment of power-management features
including energy-efficient Ethernet (EEE) have been
designed in to satisfy energy efficient environments.
