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 …

KSZ8893FQL
Single-Chip 3-Port Switch
with Fiber Support
Rev. 1.3 General Description
The KSZ8893FQL, a highly integrated single-chip 3 port
Fast Ethernet switch is designed for applications with
fiber support such as media converter. It provides two
10/100 transceivers with patented mixed-signal lowpower technology, three media access control (MAC)
units, a high-speed non-blocking switch fabric, a Layer-2
managed switch and TS-1000 OAM (Operations,
Administration and Management) V2 in a compact
solution. Backwards compatible to the TS-1000 (2002)
specification, TS-1000 V2 is an OAM sub-layer that
provides communication between CO (central office) and
CPE (customer premises equipment).
In fiber mode, one PHY unit can be configurable to
100Base-FX, 100Base-SX, or 10Base-FL fiber for
conversion to 10Base-T and 100Base-TX copper. A fiber
LED driver and post amplifier are also included for
10Base-FL and 100Base-SX applications. LinkMDВ® In copper mode, both PHY units support 10Base-T and
100Base-TX with HP Auto MDI/MDI-X for reliable
detection of and correction for straight-through and
crossover cables, and LinkMDВ® TDR-based cable …
