DATASHEET

Triple Analog Video Delay Lines

ISL59920, ISL59921, ISL59922, ISL59923

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.

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.

Features

• 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

• 20 Ld QFN package

• Pb-Free (RoHS compliant)

Applications

•Skew control for RGB video signals

• Generating programmable high-speed analog delays
