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.

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 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 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

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

forwarding table, and an on-chip frame buffer memory
