General Description

   The RTL8201CL is a single-chip/single-port PHYceiver with an MII (Media Independent Interface)/SNI (Serial Network 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).

Features
