2. General Description<br />
The RTL8201CL is a <strong>single</strong>-<strong>port</strong> Phyceiver with an MII (Media Independent Interface)/SNI (Serial Network<br />
Interface). It implements all <strong>10</strong>/<strong>10</strong>0M Ethernet Physical-layer functions including the Physical Coding Sublayer<br />
(PCS), Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD),<br />
<strong>10</strong>Base-Tx Encoder/Decoder and Twisted Pair Media Access Unit (TPMAU). A PECL interface is sup<strong>port</strong>ed to<br />
connect with an external <strong>10</strong>0Base-FX fiber optical transceiver. The <strong>chip</strong> is fabricated with an advanced CMOS<br />
process to meet low voltage and low power requirements. Further more, it is developed with on <strong>chip</strong> Digital Signal<br />
Processing technology to ensure excellent performance under all operating conditions.<br />
The RTL8201CL can be used as a Network Interface Adapter, MAU, CNR, ACR, Ethernet Hub, and Ethernet<br />
Switch. Additionally, it can also be used in any embedded system with an Ethernet MAC that needs a UTP physical<br />
connection or Fiber PECL interface to external <strong>10</strong>0Base-FX optical transceiver module.<br />
