PRODUCT DESCRIPTION
The AD8108 and AD8109 are high speed 8 × 8 video cross point switch matrices. They offer a –3 dB signal bandwidth greater than 250 MHz and channel switch times of less than 25 ns with 1% settling. With –83 dB of crosstalk and –98 dB isolation (@ 5 MHz), the AD8108/AD8109 are useful in many high speed applications. The differential gain and differential phase of better than 0.02% and 0.02° respectively along with 0.1 dB flatness out to 60 MHz make the AD8108/AD8109 ideal for video signal switching.
