KS8995MA

Integrated 5-Port 10/100 Managed Switch

Rev 2.4

General Description

Features

The KS8995MA 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. It also

provides an extensive feature set such as tag/port-based

VLAN, quality of service (QoS) priority, management, MIB

counters,dualMIIinterfacesandCPUcontrol/datainterfaces

to effectively address both current and emerging Fast Ether-

net applications.

• 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

• 1.4Gbps high-performance memory bandwidth

• 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)

The KS8995MA contains five 10/100 transceivers with pat-

entedmixed-signallow-powertechnology, fivemediaaccess

control(MAC)units, ahigh-speednon-blockingswitchfabric,

a dedicated address lookup engine, and an on-chip frame

buffer memory.

• IEEE 802.1q tag-based VLAN (16 VLANs, full-range

VID) for DMZ port, WAN/LAN separation or inter-VLAN

switch links

• VLAN ID tag/untag options, per-port basis

• Programmable rate limiting 0Mbps to 100Mbps, ingress

and egress port, rate options for high and low priority,

per-port basis in 32Kbps increments

All PHY units support 10BASE-T and 100BASE-TX.

In addition, two of the PHY units support 100BASE-FX

(ports 4 and 5).

• Flow control or drop packet rate limiting (ingress port)

• Integrated MIB counters for fully compliant statistics

gathering, 34 MIB counters per port
