KS8995XA
Integrated 5-Port 10/100 QoS Switch
Rev. 2.3
General Description
The KS8995XA is a highly integrated Layer-2 quality of
service (QoS) switch with optimized bill of materials (BOM)
cost for low port count, cost-sensitive 10/100Mbps switch
systems. It also provides an extensive feature set including
three different QoS priority schemes, a dual MII interface for
BOM cost reduction, rate limiting to offload CPU tasks,
software and hardware power-down, a MDC/MDIO control
interface and port mirroring/monitoring to effectively address
both current and emerging Fast Ethernet applications.
The KS8995XA contains five 10/100 transceivers with pat-
ented 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 addi-
tion, two of the PHY units support 100BaseFX (Ports 4 and 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
10BASE-T, 100BASE-TX and 100BASE-FX modes
(FX in Ports 4 and 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
Enable/disable option for huge frame size up to
1916 bytes per frame
Broadcast storm protection with percent 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)
QoS/CoS packets prioritization supports: per port,
802.1p and DiffServ-based
