Triple Analog Video Delay Lines

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.
