Single-Chip/Port 10/100Mbps Ethernet PHYceiver with Auto MDIX
General Description

The RTL8201EN-VC-GR is a single-chip/single-port 10/100Mbps Ethernet PHYceiver that supports:

  • MII (Media Independent Interface)
  • RMII (Reduced Media Independent Interface)
  • SNI (Serial Network Interface)

    The RTL8201EN 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
    • 10/100Mbps operation
    • Full/half duplex 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
    • Supports Interrupt function
    • 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
    • 48-pin QFN ‘Green’ package
    • Network Interface Adapter
    • MAU (Media Access Unit)
    • CNR (Communication and Network Riser)
    • ACR (Advanced Communication Riser)
    • Ethernet hub
    • Ethernet switch
    In addition, the RTL8201EN 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.
