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 differential 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 with interpolated values. (4) With a pseudo-random equiprobable sequence of HDSL pulses; 13.5dBm applied to the transformer (27dBm output from
txLINE
and txLINE
). (5) Guaranteed by design and characterization. (6) Uncancelled Echo is a measure of the total analog errors in the transmitter and receiver
sections including the effect of non-linearity and noise. See the Discussion of Specifications section of this data sheet for more information. (7) Power dissipation
includes only the power dissipated within the component and does not include power dissipated in the external loads. The AFE1205 is tested with a 1:2 line
transformer. (8) This is the settling time required for any gain change, change of rxSYNC or any change of power mode.
