The SMSC LAN9303 and LAN9303M are high-performance, small-footprint, full-featured 3-port managed Ethernet switches. Both SMSC devices are application-optimized for consumer electronic designs that have a rapid development cycle and require low-cost switching functionality, flexibility, and ease of integration. Featuring the industry’s smallest form factor 3-port switches, the SMSC LAN9303 and LAN9303M 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 second MII/RMII/Turbo MII port on the LAN9303M enables direct connectivity with home networking technologies such as MoCA®, HomePlug®, HomePNA™ (HPNA), and Optical Fiber, among others.
