August 27, 2015 Triple Analog Video Delay Lines Features The ISL59920, ISL59921, ISL59922, and ISL59923 are triple
analog delay lines that provide skew compensation between
three high-speed signals. These parts are ideal for
compensating for the skew introduced by a typical CAT-5,
CAT-6 or CAT-7 cable (with differing electrical lengths on each
twisted pair) when transmitting analog video. 30, 31, 46.5, or 62ns Total delay 1.0, 1.5, or 2.0ns Delay step increments Very low offset voltage Drop-in compatible with the EL9115 Using a simple serial interface, the ISL59920, ISL59921,
ISL59922, and ISL59923’s delays are programmable in steps
of 2, 1.5, 1, or 2ns (respectively) for up to a total delay of 62,
46.5, 31, or 30ns (respectively) on each channel. The gain of
the video amplifiers can be set to x1 (0dB) or x2 (6dB) for
back-termination. The delay lines require a В±5V supply. Low power consumption 20 Ld QFN package Pb-Free (RoHS compliant) Applications Skew control for RGB video signals 17 18 16 TESTB TESTG VSPO RIN 19
