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) This specification does not apply to the AFE1105EA. (5) With a pseudo-random equiprobable sequence of HDSL pulses;
13.5dBm applied to the transformer (27dBm output from txLINE
and txLINE
). (6) Guaranteed by design and characterization. (7) 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. (8) Power dissipation includes only the power dissipated within the component and does not include power dissipated in the external
loads. The AFE1105 is tested with a 1:2 line transformer, but will typically be used with a 1:2.3 line transformer, this will slightly increase power dissipation.
