The KSZ8462 ETHERSYNCH™ 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.
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.
The wire−speed, store−and−forward switching fabric provides a full complement of quality-of-service (QoS) and congestion control features optimized for real−time Ethernet.
The KSZ8462 includes all the functions of a 10/100BASE−T/TX/FX switch system which combines a switch engine, frame buffer management, address lookup table, queue management, MIB counters, media access controllers (MAC) and PHY transceivers
non-−blocking store−and−forward switch fabric assures fast packet delivery by utilizing 1024 entry forwarding table
Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port
MIB counters for fully-compliant statistics gathering − 34 counters per port
Loopback modes for remote failure diagnostics
Rapid spanning tree protocol support (RSTP) for topology management and ring/linear recovery
Two integrated IEEE 802.3/802.3u compliant Ethernet transceivers supporting 10BASE-T and 100BASE-TX
Copper and 100BASE-FX fiber mode support in the KSZ8462FHL
Copper mode support in the KSZ8462HL
On−chip termination resistors and internal biasing for differential pairs to reduce power
HP Auto MDI/MDI−X crossover support eliminating the need to differentiate between straight or crossover cables in applications
