Product Summary
The 88E1121RA0-TFE1C000 is a dual-port Gigabit Ethernet (GbE) transceiver. It is a physical layer (PHY) device containing two independent GbE transceivers on a single monolithic IC. The transceiver implement the Ethernet PHY portion of the 1000BASE-T, 100BASE-TX, and 10BASE-T standards and are compliant with IEEE 802.3u Auto-Negotiation. The 88E1121RA0-TFE1C000 is manufactured using standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair. The 88E1121RA0-TFE1C000 supports the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to a Media Access Controller (MAC)/switch port. The 88E1121RA0-TFE1C000 also integrates Media Dependent Interface (MDI) termination resistors and capacitors into the PHY. It is ideal for IP phones and other applications requiring low power and a small footprint.
