Single-Chip/Port 10/100Mbps Ethernet PHYceiver with Auto MDIX
General Description
The RTL8201E(L) is a single-chip/single-port 10/100Mbps Ethernet PHYceiver that supports:
  • MII (Media Independent Interface)
  • RMII (Reduced Media Independent Interface; RTL8201E(L)-VC and RTL8201E-VCR only)
  • SNI (Serial Network Interface)
The RTL8201E(L) 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.
  • Supports MII and 7-wire SNI (Serial Network Interface)
  • Supports RMII mode (RTL8201E(L)-VC and RTL8201E-VCR only)
  • 10/100Mbps operation
  • Twisted pair or fiber mode output
  • Auto-Negotiation
  • Supports power down mode
  • Supports operation under Link Down Power Saving mode
  • Supports Base Line Wander (BLW) compensation
  • Supports auto MDIX
  • Supports repeater mode
  • Automatic Polarity Correction
  • Supports Interrupt function (RTL8201EL-VC only)
  • Adaptive Equalization
  • Network status LEDs
  • Flow control support
  • 25MHz crystal/oscillator as clock source
  • IEEE 802.3/802.3u compliant
  • Low power supply, 1.2V, and 3.3V; 1.2V is generated by an internal regulator
  • 0.11µm CMOS process
  • Packages:
    • 32-pin QFN ‘Green’ package (RTL8201E)
    • 48-pin LQFP ‘Green’ package (RTL8201EL)
  • Network Interface Adapter
  • MAU (Media Access Unit)
  • CNR (Communication and Network Riser)
  • ACR (Advanced Communication Riser)
  • Ethernet hub
  • Ethernet switch
In addition, the RTL8201E(L) can be used in any embedded system with an Ethernet MAC that needs a UTP physical connection or Fiber PECL interface to an external 100Base FX optical transceiver module.
