KSZ8842-PMQL/PMBL

Two-Port Ethernet Switch with PCI Interface

QoS/CoS Packets Prioritization Support

Features

• Per Port, 802.1p and DiffServ Based

Switch Management

• Re-Mapping of 802.1p Priority Field on a Per Port

Basis

• Non-Blocking Switch Fabric Assures Fast Packet

Delivery by Utilizing a 1K Entry MAC Address

Look-Up Engine and a Store-and-Forward

Architecture

Power Modes, Packaging, and Power Supplies

• Full-chip Hardware Power-Down (Register Con-

figuration not Saved) Provides for Low Power

Dissipation

• Fully Compliant with the IEEE802.3u Standards

• Full-Duplex IEEE 802.3x Flow Control (Pause)

with Force Mode Option

• Per Port-Based Software Power-Save on PHY

(Idle Link Detection, Register Configuration Pre-

served)

• Half-Duplex Backpressure Flow Control

Advance Switch Management

• Single Power Supply: 3.3V

• IEEE 802.1Q VLAN Support for Up to Sixteen

Goups (Full-Range of VLAN IDs)

• 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

• VLAN ID Tag/Untag Options, Per Port Basis

• IEEE 802.1p/Q Tag Insertion or Removal On a

Per-Port Basis (Egress)

Additional Features

• Programmable Rate Limiting at the Ingress and

Egress Port

• In Addition to Offering All of the Features of an

Integrated Layer-Two Managed Switch, the

KSZ8842-PMQL/PMBL Offers:

• Broadcast Storm Protection

• IEEE 802.1d Spanning Tree Protocol Support

• MAC Filtering Function to Filter Unicast Packets

• Unknown MAC Address Forwarding Function

• Repeater Mode Capabilities to Allow for Cut

Through in Latency Critical Industrial Ethernet or

Embedded Ethernet Applications

• Direct Forwarding Mode Enabling the Processor

to Identify the Ingress Port and to Specify the

Egress Port

• Dynamic Buffer Memory Scheme Essential for

Applications Such as Video Over IP Where Image

Jitter is Unacceptable

• IGMP v1/v2 Snooping Support for Multicast

Packet Filtering

• Two-Port Switch with a 32-Bit/33 MHz PCI

Processor Interface.

• Microchip LinkMD^®Cable Diagnostics to

Determine Cable Length, Diagnose Faulty

Cables, and Determine Distance-to-Fault

• IPV6 Multicast Listener Discovery (MLD) Snoop-

ing support

Monitoring

• Port Mirroring/Monitoring/Sniffing: Ingress and/or

Egress Traffic to Any Port

• Hewlett Packard (HP) Auto MDI-X Crossover with

Disable and Enable Options

• Management Information Base (MIB) Counters

for Fully Compliant Statistics Gathering: 32 MIB

Counters Per Port

• Four Priority Queues to Handle Voice, Video,

Data, and Control Packets

• Ability to Transmit and Receive Jumbo Frame

Sizes Up to 1916 Bytes

• 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.)
