The ISL59920 ia a triple analog delay line that provides skewcompensation between three high-speed signals. Theseparts are ideal for compensating for the skew introduced bya typical CAT-5 cable (with differing electrical lengths oneach twisted pair) when transmitting analog video.Using a simple serial interface, the ISL59920’s delay isprogrammable in steps of 2ns up to a total delay of 62ns oneach channel. The gain of the video amplifiers can be set tox1 (0dB) or x2 (6dB) for back-termination. The delay linesrequire a ±5V supply.
