In addition to offering all of the features of an integrat-
ed Layer 2 managed switch:
2-port switch with 32 bit/33MHz PCI bus for differ-
ent host processor interfaces
Fully compliant to the IEEE802.3u standard
Repeater mode capabilities to allow for ‘cut-thru’
in latency critical Industrial Ethernet or Embedded
Ethernet applications
Dynamic buffer memory scheme
– Essential for applications such as Video over IP
where image jitter is unacceptable
Micrel LinkMDTM cable diagnostic capabilities to
determine cable length, determine distance to fault,
and to diagnose faulty cables
HP Auto MDIX crossover with disable and enable
option
Industrial temperature support: –40oC to +85oC
Four priority queues to handle voice, video, data,
and control packets

Description
The KSZ8842-PMQL is the industry’s rst 2-port switch
with a PCI CPU interface. An Industrial Temperature
grade part, the KSZ8842-PMQLI will also available from
Q1, 2006. The KSZ8842P is a proven, 4th generation,
integrated, fully managed Layer 2 switch that is entirely
compliant to IEEE802.3u standards.
The KSZ8842P can be congured as a low-latency re-
peatertoallowfor‘cutthru’inlatencycriticalEmbeddedor
IndustrialEthernetapplications.Forindustrialautomation
applications, it runs in half-duplex mode.
TheKSZ8842Poffersanextensivefeaturesetthatincludes
tag/port-based VLAN, QoS priority management, MAC
ltering function, MIB counters, and CPU control/data
interfaces to effectively address both current and emerg-
ing Fast Ethernet applications.
The KSZ8842P contains two 10/100 transceivers with
patented mixed-signal low-power technology, two 1K
entry media access control (MAC) units, a separate
DMA channel, a high-speed non-blocking switch fabric,
a dedicated 1K entry forwarding table, and an on-chip
frame buffer memory.
