KS8893M/ML/MI

Integrated 3-Port 10/100 Managed Switch with PHYs

Preliminary Data Sheet Rev. 1.0

General Description

The KS8893M contains two 10/100 transceivers with

patented mixed-signal low-power technology, three

media access control (MAC) units, a high-speed

non-blocking switch fabric, a dedicated address

lookup engine, and an on-chip frame buffer memory.

The KS8893M, a highly integrated layer 2 managed

switch, is designed for low port count, cost-sensitive

10/100 Mbps switch systems. It offers an extensive

feature set that includes rate limiting, tag/port-based

VLAN, QoS priority, management, management

information base (MIB) counters, MII/SNI, and CPU

control/data interfaces to effectively address both

current and emerging Fast Ethernet applications.

Both PHY units support 10BASE-T and 100BASE-

TX. In addition, one PHY unit supports 100BASE-

FX.

The KS8893ML is the single power supply version

with all the identical rich features of the KS8893M.
