KSZ8873RLLI-TR

The KSZ8873FLL are highly-integrated 3-port switches on a chip ICs in the industry’s smallest footprint. 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, software power down, per port power down and the energy detect mode that shuts downs the transceiver when a port is idle. KSZ8873FLL also offers a by-pass mode. In this mode, the processor connected to the switch through the MII interface can be shut down without impacting the normal switch operation. The configurations provided by the KSZ8873 family enables the flexibility to meet requirements of different applications:
KSZ8873FLL: Two 100BASE-FX transceivers and one MII interface. The device is available in RoHS-compliant 64-pin LQFP package. Industrial-grade and qualified AEC-Q100 Automotive-grade version are also available.

Advanced Switch Features IEEE 802.1q VLAN support for up to 16 groups VLAN ID tag/untag options, per port basis IPv4/IPv6 QoS support Comprehensive Configuration Register Access Serial management interface (SMI) to all internal registers MII management (MIIM) interface to PHY registers QoS/CoS Packet Prioritization Support Per port, 802.1p and DiffServ-based Proven Integrated 3-Port 10/100 Ethernet Switch 3rd generation switch with three MACs and two PHYs fully compliant with IEEE 802.3u standard MII interface supports both MAC mode and PHY mode Switch Monitoring Features Low Power Dissipation Transceiver power 3.3V for VDDA_3.3 Industrial Temperature Range: -40°C to +85°C Available in 64-Pin LQFP, Lead-free package
