NOTES: (1) With a balanced differential signal, the positive input is 180
°
out of phase with the negative input, therefore, the actual voltage swing about the common-
mode voltage on each pin is
±
1.5V to achieve a total input range of
±
3.0V or 6Vp-p. (2) FSR is Full-Scale Range. (3) The output data is available at twice the symbol
rate. (4) With a pseudo-random equiprobable sequence of HDSL pulses; 13.5dBm applied to the transformer (16.5dBm output from txLINEP and txLINEN). (5) See
the Discussion of Specifications section of this data sheet for more information. (6) Functionality only is guaranteed over temperature range.
