Applications Information
The ISL59920, ISL59921, ISL59922, and ISL59923 are triple
analog delay lines that provide skew compensation between
three high-speed signals. These devices compensate for time
skew introduced by a typical CAT-5, CAT-6 or CAT-7 cable with
differing electrical lengths (due to different twist ratios) on each
pair. Via their SPI interface, these devices can be programmed to
independently compensate for the three different cable delays
while maintaining 80MHz bandwidth at their maximum setting.
There are four different variations of the ISL5992x (ISL5992x will
be used when talking about characteristics that are common to
all four devices).
