Microchip Technology LAN8830 Gigabit Ethernet Transceiver RGMII

     Microchip Technology LAN8830 Gigabit Ethernet Transceiver integrated with RGMII, three-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical layer transceiver, Designed to transmit and receive data over standard CAT-5, CAT-5e, and CAT6 unshielded twisted pair (UTP) cables. The LAN8830 features RGMII(Simplified Gigabit Media Independent Interface) for connecting Ethernet switches, microcontrollers, or microprocessors. In addition, the Embedded Ethernet Media Access Controller (MAC) provides the RGMIII interface for 1000Mbps or 10/100Mbps data transfer.

     Microchip LAN8830 transceiver reduces board cost and simplifies board layout by using on-chip terminal resistors for four differential pairs. In addition, the LAN8830 integrates an LDO controller to drive a low-cost MOSFET that provides a 1.2V core.

     The device provides diagnostic capabilities to enable system startup and debugging during production testing and product deployment. The parameterized NAND tree supports fault detection between LAN8830 I/ o and boards. Cable diagnosis based on LinkMD tdr can identify faulty copper cables. Remote and local loopback capabilities validate analog and digital data paths. The LAN8830 comes in a RoHS-compliant 48-pin QFN package
