Microchip | KSZ8995X

The KSZ8995X is a highly-integrated layer-2 QoS(quality of service) switch with two MACs MII or RMII interfaces available in surface mount PQFP-128 package.

This device 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.

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 nonblocking configuration
• 10BaseT, 100BaseTX and 100BaseFX 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
• Port-based VLAN support
• MDC and MDI/O interface support to access the MII
• PHY control registers (not all control registers)
• MII local loopback support

Applications:

• Broadband gateway/firewall/VPN
• Integrated DSL or cable modem multi-port router
• Wireless LAN access point plus gateway
• Home networking expansion
• Standalone 10/100 switch
• Hotel/campus/MxU gateway
• Enterprise VoIP gateway/phoneFTTx customer premise equipment
