Description
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.
Applications
- Skew Control for RGB Video Signals
- Generating Programmable High-speed Analog Delays
