RTL8201E(L)
Datasheet
1. General Description
The RTL8201E(L) is a single-chip/single-port Fast Ethernet PHYceiver that supports:
• MII (Media Independent Interface)
• RMII (Reduced Media Independent Interface; RTL8201E(L)-VB only)
• 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), with an auto MDIX function, 10Base-Tx Encoder/Decoder, and Twisted-Pair Media Access Unit
(TPMAU).
A PECL (Pseudo Emitter Coupled Logic) interface is supported to connect with an external 100Base-FX
fiber optical transceiver. The chip utilizes an advanced CMOS process to meet low voltage and low
power requirements. With on-chip DSP (Digital Signal Processing) technology, the chip provides
excellent performance under all operating conditions.
