KS8995X Product Brief
Revision 1.08
Integrated 5-Port 10/100 QoS Switch
The KS8995X is a highly integrated layer-2 QoS
switch with optimized BOM (Bill-Of-Materials) cost for
low port count, cost-sensitive 10/100Mbps switch
systems. It also provides an extensive feature set including
three different QoS priority schemes, dual MII interface
for BOM cost reduction, programmable rate limiting to
offload CPU tasks, software & hardware power-down ,
MDC/MDIO control interface and port monitoring to
effectively address both current and emerging Fast
Ethernet applications.
The KS8995X contains five 10/100 transceivers with
patented mixed-signal low-power technology, five MAC
(Media Access Control) 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 100BaseTX.
In addition, two of the PHY units support 100BaseFX
(Ports 4 & 5).

Features
Integrated switch with five MACs and five Fast Ethernet
transceivers fully compliant to IEEE 802.3u standard
Shared memory based switch fabric with fully non-
blocking configuration
10BaseT, 100BaseTX and 100BaseFX modes (FX
in Ports 4 & 5)
Dual MII configuration: MII-Switch (MAC or PHY
mode MII) and MII-P5 (PHY mode MII)
VLAN ID tag/untag options, per-port basis
Programmable rate limiting, ingress and egress port, rate
options for high and low priority, per port basis
Flow control or drop packet rate limiting (ingress port)
Broadcast storm protection with % control–global and
per-port basis
Optimization for fiber-to-copper media conversion
Full-chip hardware power-down support (register
configuration not saved)
Per-port based software power-save on PHY (idle link
detection, register configuration preserved)
