RTL8201L datasheet



The RTL8201L is a single-port Phyceiver with an MII (MediaIndependent 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 anadvanced 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.
