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. KS8995XA 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 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 100BaseFX (Ports 4 and 5).
