Switch with PHYs

Rev 1.06

General Description

The KSZ8993M, 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 tag/port-based

VLAN, quality of service (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.

The KSZ8993M 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.

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

TX. In addition, one of the PHY unit supports

100BASE-FX.

The KSZ8993ML is the single supply version with all

the identical rich features of the KSZ8993M.
