(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

(1) The given differential input signal swing is measured at the input of the interconnect line. The high frequency components of the signal
at the output of the interconnect line (which is connected the input pins DIN+/DIN– of the TLK4211EA) may be attenuated by 0 dB up to
12 dB at 2.1 GHz dependent of the interconnect line length.
