Compliant

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

Ω or 75 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.
