KSZ8862-16/32MQL

2-Port Ethernet Switch with Non-PCI Interface

and Fiber Support

Rev 3.1

General Description

The KSZ8862M is 2-port switch with non-PCI CPU

interface and fiber support, and is available in 8/16-bit

and 32-bit bus designs (see Ordering Information). This

datasheet describes the KSZ8862M non-PCI CPU

interface chip.

LinkMD

In copper mode, port 2 supports 10/100BASE-T/TX with

HP Auto MDI/MDI-X for reliable detection of and

correction for straight-through and crossover cables.

The KSZ8862M is the industry’s first fully managed, 2-

port switch with a non-PCI CPU interface and fiber

support. It is based on a proven, 4^thgeneration,

integrated Layer-2 switch, compliant with IEEE 802.3u

standards.

Reflectometry (TDR)-based function is also available for

determining the cable length, as well as cable

diagnostics for identifying faulty cabling.

For industrial applications, the KSZ8862M can run in

half-duplex mode regardless of the application.

The KSZ8862M 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.

In fiber mode, port 1 can be configurable to either

100BASE-FX or 100BASE-SX/10BASE-FL.

The LED driver and post amplifier are also included for

10Base-FL and 100Base-SX applications.

The KSZ8862M contains: Two 10/100 transceivers with

patented, mixed-signal, low-power technology, two

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.
