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
• Low Power Consumption
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 ±5V
supply.
• 20 Ld QFN Package
• Pb-Free (RoHS Compliant)
Applications
• Skew Control for RGB Video Signals
• Generating Programmable High-speed Analog Delays

NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations).
Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J
STD-020.
