SP-10 100ETHERNET-S40LL is a single-port DSP-based Fast Ethernet Transceiver. It contains all the active circuitry
required to convert data stream to and from a Media Access Control (MAC) and from and to the physical
media. It incorporates IEEE 802.3u auto-negotiation and supports 100Base-TX and 10BASE-T networks over
twisted-pair cable in full-duplex or half-duplex mode. Both the Media Independent Interface(MII) and Reduced
Media Independent Interface (RMII) are supported. It supports Auto Crossover function to simplify
Plug-n-Play to IA relative products.
