KSZ8893MQL/MBL
Integrated 3-Port 10/100 Managed
Switch with PHYs
Rev. 1.6
with patented mixed-signal low-power technology,
three media access control (MAC) units, a highspeed non-blocking switch fabric, a dedicated
address lookup engine, and an on-chip frame buffer
memory.
Both PHY units support 10BASE-T and 100BASETX. In addition, one PHY unit supports 100BASE-FX.
The KSZ8893MQL/MBL comes in a lead-free
package, and is also available in industrial
temperature-grade
KS8893MQLI/MBLI
and
Automotive-grade KSZ8893 MQL AM. (See Ordering
Information). General Description
The KSZ8893MQL/MBL, 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,
RMII/MII/SNI, and CPU control/data interfaces to
effectively address both current and emerging Fast
Ethernet applications.
The KSZ8893MQL/MBL contains two 10/100
transceivers ___________________________________________________________________________________________________ Functional Diagram HP AUTO
