3-Port 10/100 Managed Ethernet Switch with Dual MII/RMII/Turbo MII
| Status: | Active |
|---|---|
| Series: | LAN9355 |
| RoHS: | Compliant |
Featuring the industry's smallest form factor 3-port switch, the LAN9355/9355i 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 virtual PHY feature mimics a single PHY connection through the MII/RMII/Turbo MII interface to the host SoC, which can reduce 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.
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 LAN9354 complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol, IEEE 802.3az Energy Efficient Ethernet (EEE) (100Mbps only), 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.
The LAN9355/9355i switch combines all of the functions of a 10/100 system, including the switch fabric, packet buffers, buffer management, MACs, PHY transceivers and optional serial management functions. Both devices comply with IEEE 802.3 10BASE-T and 100BASE-TX Ethernet protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications. Supports Fiber Interface through SFP and SFF Physical medium
