The TLK3118 is a flexible, redundant XAUI serial transceiver that is compliant to 10-Gbps Ethernet XAUI specification. The TLK3118 provides high-speed bi-directional point-to-point data transmissions with up to 12.5 Gbps of raw data transmission capacity. The primary application of this device for use in backplanes and front panel connections requiring redundant 10Gbps connections over controlled impedance media of approximately 50 . The transmission media can be printed circuit board (PCB) 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 into the lines.

The TLK3118 performs the parallel-to-serial, serial-to-parallel conversion, and clock extraction functions for a physical layer interface.
