The TLK1201A/TLK1201AI gigabit ethernet transceiver provides for ultrahigh-speed, full-duplex, point-to-point data transmissions. This device is based on the timing requirements of the 10-bit interface specification by the IEEE 802.3 gigabit ethernet specification and is also compliant with the ANSI X3.230-1994 (FC-PH) fibre channel standard. The device supports data rates from 0.6 Gbps to 1.3 Gbps. The primary application of the transceiver is to provide building blocks for point-to-point baseband data transmission over controlled impedance media of 50 or 75 . The transmission media can be printed-circuit board traces, copper cables, or fiber-optical media. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment. PowerPAD is a trademark of Texas Instruments.
