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.
The KSZ8862M is the industry’s first fully managed, 2port switch with a non-PCI CPU interface and fiber
th
support. It is based on a proven, 4 generation,
integrated Layer-2 switch, compliant with IEEE 802.3u
standards.
For industrial applications, the KSZ8862M can run in
half-duplex mode regardless of the application.
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. В® 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.
