Microchip Technology, Inc. 3-Port 10/100 Managed Ethernet Switch LAN9353

Microchip's LAN9353/LAN9353i is a high-performance, small-footprint, full-featured 3-port managed Ethernet switch. This device is application-optimize d for consumer, embedded and Industrial electronic designs which require a highly integrated, cost effective device with switching functionality, flexibility and ease of integration. The LAN9353/9353i supports compact PCB design and MII/RMII/Turbo MII (Media Independent, Reduced Media Independent and Turbo Media Independent Interfaces). This device supports Turbo MII mode to accomplish network speeds up to 200 Mbps. The LAN9353 can also be configured to support Dual RMII operation. The virtual PHY feature mimics a single PHY connection through the MII/RMII/Turbo MII interface to the host SoC, which reduces software development time. This feature also allows system designers to swap the single PHY and Ethernet switch to create multiple SKUs from the same software driver. The LAN9353 combines all the functions of a 10/100 switch system, including the Switch Fabric, packet buffers, Buffer Manager, Media Access Controllers (MACs), PHY transceivers, and serial management. IEEE 1588v2 is supported via the integrated IEEE 1588v2 hardware time stamp unit, which supports end-to-end and peer-to-peer transparent clocks. The LAN9353 complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol, IEEE 802.3az Energy Efficient Ethernet (EEE) (100Mbpsonly), and 802.1D/802.1Q network management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications. 100BASE-FX is supported via an external fiber transceiver. This device complies with IEEE 802.3 10BASE-T and 100BASE-TX Ethernet protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications.
