General Description
The KSZ8842-series of 2-port switches includes PCI and
non-PCI CPU interfaces. This datasheet describes the
KSZ8842-PMQL/PMBL
PCI
CPU
interface
chips.
KSZ8842-PMQL is PQFP package chip, KSZ8842-PMBL
is
LFBGA
package
chip.
For
information
on
the
KSZ8842-MQL/MBL CPU non-PCI interface switches,
refer to the KSZ8842-MQL/MBL datasheet.
The KSZ8842-PMQL/PMBL is the industry’s first fully
managed 2-port switch with a 32 bit/33MHz PCI
processor interface. It is a proven, 4th generation,
integrated Layer 2 switch that is compliant with the IEEE
802.3u standard. An industrial temperature grade version
of the KSZ8842-PMQL/PMBL, also can be ordered the
KSZ8842-PMQLI/PMBL AM.
The KSZ8842-PMQL/PMBL can be configured as a
switch or as a low-latency (<310 nanoseconds) repeater
in
latency-critical,
embedded
or
industrial
Ethernet
applications. For industrial automation applications, the
LinkMD
KSZ8842-PMQL/PMBL can run in half-duplex mode
regardless of the application. The KSZ8842-PMQL/PMBL
offers an extensive feature set that includes tag/port-
based
VLAN,
quality
of
service
(QoS)
priority
management,
management
information
base
(MIB)
counters, and CPU control/data interfaces to effectively
address Fast Ethernet applications.
The
KSZ8842-PMQL/PMBL
contains
two
10/100
transceivers
with
patented,
mixed-signal,
low-power
technology three media access control (MAC) units, a
direct memory access (DMA) channel, a high-speed,
non-blocking,
switch
fabric,
a
dedicated
1K
entry
forwarding table, and an on-chip frame buffer memory.
