Features
Switch Management
Non-blocking switch fabric assures fast packet delivery
by utilizing a 1K entry MAC Address look-up engine and
a store-and-forward architecture
Fully compliant with IEEE802.3u standards
Full-duplex IEEE 802.3x flow control (Pause) with force
mode option
Half-duplex back pressure flow control
Advanced Switch Management
IEEE 802.1Q VLAN support for up to 16 groups (full-
range of VLAN IDs)
VLAN ID tag/untag options, per port basis
IEEE 802.1p/Q tag insertion or removal on a per-port
basis (egress)
Programmable rate limiting at the ingress and egress
port
Broadcast storm protection
IEEE 802.1d spanning tree protocol support
MAC filtering function to filter unicast packets
Unknown MAC address forwarding function
Direct forwarding mode enabling the processor to
identify the ingress port and to specify the egress port
IGMP v1/v2 snooping support for multicast packet
filtering
IPV6 Multicast Listener Discovery (MLD) snooping
support
Monitoring
Port mirroring/monitoring/sniffing: ingress and/or egress
traffic to any port
Management information base (MIB) counters for fully
compliant statistics gathering: 32 MIB counters per port
Loop back modes for remote failure diagnostics
Comprehensive Register Access
There are three kinds of register groups:
The PCI configuration registers are used to initialize
and configure the PCI interface
The PCI control/status registers are used to
communicate between the host and KSZ8842-
PMQL/PMBL
Switch registers are used to support transceiver control
and status. They are configurable on-the-fly (port-
priority, 802.1p/d/Q, etc.)
QoS/CoS Packets Prioritization Support
Per port, 802.1p and DiffServ based
Re-mapping of 802.1p priority field on a per port basis
Power Modes, Packaging, and Power Supplies
Full-chip hardware power-down (register configuration
not saved) provides for low power dissipation
Per port-based software power-save on PHY (idle link
detection, register configuration preserved)
Single power supply: 3.3V
Commercial Temperature Range: 0°C to +70°C
Industrial Temperature Range: –40°C to +85°C
Available in 128-pin PQFP and 100-ball LFBGA
Additional Features
In addition to offering all of the features of an integrated
Layer-2 managed switch, the KSZ8842-PMQL/PMBL
offers:
Repeater mode capabilities to allow for cut through 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
2-Port switch with a 32-bit/33MHz PCI processor
interface.
Micrel LinkMD cable diagnostics to determine cable
length, diagnose faulty cables, and determine distance-
to-fault
Hewlett Packard (HP) Auto MDI-X crossover with
disable and enable options
Four priority queues to handle voice, video, data, and
control packets
Ability to transmit and receive jumbo frame sizes up to
1916 bytes
Applications
Video Distribution Systems
High-end Cable, Satellite, and IP set-top boxes
Video over IP
Voice over IP (VoIP) and Analog Telephone Adapters
(ATA)
Industrial Control in Latency Critical Applications
Motion Control
Industrial Control Sensor Devices (Temperature,
Pressure, Levels, and Valves)
Security and Surveillance Cameras
Markets
Fast Ethernet
Embedded Ethernet
Industrial Ethernet
