KS8995MA/FQ
Integrated 5-Port 10/100 Managed Switch
Rev. 3.0 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/portbased 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 on
ports 4 and 5 for KSZ8995MA, two of the PHY units
support 100BASE-FX on ports 3 and 4 for KSZ8995FQ.
