RTL8201FR(I)-VD-CG数据手册Realtek中文资料规格书

描述 Description

The RTL8201FR(I)-VD-CG is a single-chip/single-port 10/100Mbps Ethernet PHYceiver that supports RMII (Reduced Media Independent Interface).
The RTL8201FR(I)-VD-CG 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). The RTL8201FR(I)-VD-CG also supports auto MDIX.
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.
