Introduction

The SR8201F-VB-CG, SR8201FL-VB-CG, and SR8201FN-VB-CG are single-chip/single-port 10/100Mbps Ethernet PHYceivers that support:

• MII (Media Independent Interface)
• RMII (Reduced Media Independent Interface)

The SR8201F/FL/FN implement 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 SR8201F/FL/FN support 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.
