The TLK3138 is an eight channel serial transceiver. It is compliant with the 10Gbps Ethernet XAUI specification. The TLK3138 provides 10 Gbps high-speed bi-directional point-to-point data transmission. The primary application of this device is in backplanes and front panel connections requiring dual/redundant 10Gbps connections over controlled impedance media of approximately 50Ω. 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 TLK3138 performs the parallel-to-serial, serial-to-parallel conversion, and clock extraction functions for a physical layer interface.
