2. General Description
The RTL8201(L) is a single-port Phyceiver with an MII (Media Independent Interface). It implements all 10/100M Ethernet
Physical-layer functions including the Physical Coding Sublayer (PCS), Physical Medium Attachment (PMA), Twisted Pair
Physical Medium Dependent Sublayer (TP-PMD), 10Base-Tx Encoder/Decoder and Twisted Pair Media Access Unit
(TPMAU). It is fabricated with an advanced CMOS process to meet low voltage and low power requirements.
The RTL8201(L) can be used as a Network Interface Adapter, MAU, CNR, ACR, Ethernet Hub, Ethernet Switch.
Additionally, it can be used in any embedded system with an Ethernet MAC that needs a twisted pair physical connection.
