KSZ8873 Ethernet Switch Controller

Microchip's integrated 3-port 10/100 managed switch with PHYs

Micrel's KSZ8873 Ethernet Switch ControllerMicrochip's KSZ8873MLL/FLL/RLL are highly integrated 3-port switch on a chip ICs in one of the industry's smallest footprints. They are designed to enable a new generation of low port count, cost-sensitive, and power efficient 10/100Mbps switch systems. Low power consumption, advanced power management, and sophisticated QoS features (e.g., IPv6 priority classification support) make these devices ideal for IPTV, IP-STB, VoIP, automotive, and industrial applications.

The KSZ8873 family is designed to support the GREEN requirement in today's switch systems. Advanced power management schemes include hardware power down and the energy detect mode, which shuts downs the transceiver when a port is idle.

Features Applications
  • 2Kbyte packet size support
  • Port 1 and Port 2 by-pass mode
  • 4-queue (per port) traffic prioritization, based on port, 802.1p, 802.1Q VLAN tags, or differential services (both Ipv4 and Ipv6 priority classification)
  • Source address filtering
  • Internal generated RMII 50MHz clock
  • LinkMD® TDR-based diagnostics
  • IPTV POF
  • SOHO residential gateway
  • Broadband gateway / firewall / VPN
  • Integrated LAN access point + gateway
  • Standalone 10/100 switch
  • VoIP phone
  • Set-top/game box
  • Automotive
  • Industrial control
Benefits
  • Ethernet traffic between Port 1 and Port 2 are sustained while the MII interface (Port 3) is shut down, allowing the device connected to the MII interface to enter a power saving mode
  • Allows identification of common cabling problems, including those not addressed by IEEE. Simplifies network deployment and reduces network downtime.
  • Enables the implementation of Ethernet ring network for industrial control and automotive applications
  • Facilitates large package size requirement in new Ethernet applications
  • Eliminates expensive external 50MHz oscillator for the RMII mode
  • Enables implementation of advanced QoS policies
