LAN9303/9303M: Industry’s Smallest 3-port 10/
100Managed Ethernet Switches with Single/
DualMII/RMII/Turbo MII Support
SMSC’s LAN9303 and LAN9303M are high-performance, small-footprint, full-featured 3-port managed Ethernet switches. Both devices are application-optimized for consumer electronics designs which have a rapid development cycle and require low-cost switching functionality, flexibility and e
ase of integration.
Featuring the industry’s smallest form factor 3-port switches, the LAN9303/9303M support compact PCB design and single (LAN9303) or dual (LAN9303M) MII/RMII/Turbo MII (Media Independent, Reduced Media Independent and Turbo Media Independent Interfaces).
The LAN9303M’s second MII/RMII/Turbo MII port enables direct connectivity with home networking technologies such as MoCA, HomePlug, HomePNA™ (HPNA) and Optical Fiber, among others. Both devices support 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. Additionally, the LAN9303/9303M offer the industry’s highest (±8kV/
15kV) perport ESD protection.
