Product Summary
The 88E1121RA0-TFE1 dual-port Gigabit Ethernet (GbE) transceiver is a physical layer (PHY) device containing two independent GbE transceivers on a single monolithic IC. The 88E1121RA0-TFE1 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-TFE1 is ideal for IP phones and other applications requiring low power and a small footprint. In an IP phone, where board space is constrained, the integrated resistor scheme on the 88E1121R allows for shorter MDI traces and thus improved IEEE template performance. Additional applications include DVRs, game consoles, NAS appliances, and workstation or desktop PCs.
