KSZ8842-PMQL/PMBL
2-Port Ethernet Switch with PCI Interface
Rev.1.5 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 (
