SP-10_100_Ethernet-S28HKMG 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 to and from the physical media. It incorporate IEEE 802.3u auto-negotiation, supporting 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.
