General Description:

The RTL8201F-VB-CG, RTL8201FL-VB-CG, and RTL8201FN-VB-CG are single-chip/single-port10/100Mbps Ethernet PHYceivers that support:

• MII (Media Independent Interface)

• RMII (Reduced Media Independent Interface) 

The RTL8201F/FL/FN implement all 10/100M Ethernet Physical-layer functions including the PhysicalCoding Sublayer (PCS), Physical Medium Attachment (PMA), Twisted Pair Physical Medium DependentSublayer (TP-PMD), 10Base-TX Encoder/Decoder, and Twisted-Pair Media Access Unit (TPMAU). TheRTL8201F/FL/FN support auto MDIX.A PECL (Pseudo Emitter Coupled Logic) interface is supported to connect with an external 100Base-FXfiber optical transceiver. The chip utilizes an advanced CMOS process to meet low voltage and lowpower requirements. With on-chip DSP (Digital Signal Processing) technology, the chip providesexcellent performance under all operating conditions.
