RTL8201DL(Rev1_1) Datasheet PDF - Realtek Semiconductor

General Description

The RTL8201DL is a single-chip/single-port PHYceiver that supports:

• MII (Media Independent Interface)

• RMII (Reduced 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 (TPPMD), 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.
