DESCRIPTION
The TLK1211RCP 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
Ω.
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.
