KS8995MA/FQ
Integrated 5-Port 10/100 Managed Switch
Rev 2.9
General Description
The KS8995MA/FQ is a highly integrated Layer 2
managed switch with optimized bill of materials (BOM)
cost for low port count, cost-sensitive 10/100Mbps
switch systems with both copper and optic fiber media.
It also provides an extensive feature set such as
tag/port-based VLAN, quality of service (QoS) priority,
management, MIB counters, dual MII interfaces and
CPU control/data interfaces to effectively address both
current and emerging fast Ethernet applications.
The KS8995MA/FQ contains five 10/100 transceivers
with patented mixed-signal low-power technology, five
media access control (MAC) units, a high-speed non-
blocking switch fabric, a dedicated address lookup
engine, and an on-chip frame buffer memory.
All PHY units support 10BASE-T and 100BASE-TX.
In addition, two of the PHY units support 100BASE-FX
(KS8995MA is ports 4 and 5, KS8995FQ is port 3 and
port 4).
