4.2.2.2 Base Line Wander Compensation
The DP83848VYB is completely ANSI TP-PMD compliant
and includes Base Line Wander (BLW) compensation. The
BLW compensation block can successfully recover the TP-
PMD defined “killer” pattern.
BLW can generally be defined as the change in the average
DC content, relatively short period over time, of an AC cou-

pled digital transmission over a given transmission medium.
(i.e., copper wire).
BLW results from the interaction between the low frequency
components of a transmitted bit stream and the frequency re-
sponse of the AC coupling component(s) within the transmis-
sion system. If the low frequency content of the digital bit
stream goes below the low frequency pole of the AC coupling
