GENERAL DESCRIPTION

The AD8120 is a triple broadband skew-compensating delay line that corrects for time mismatch between video signals incurred by transmission in unshielded twisted pairs of Category 5 and Category 6 type cables. Skew between the individual pairs exists in most types of multipair UTP cables due to the different twist rates that are used for each pair to minimize crosstalk between pairs. For this reason, some pairs are longer than others, and in long cables, the difference in propagation time between two pairs can be well into the tens of nanoseconds.
