Description

The AD8108 / AD8109 are high speed 8 × 8 video crosspoint 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.

Features
1. 8 × 8 high speed nonblocking switch arrays
2. Serial or parallel programming of switch array
3. Serial data out allows daisy-chaining of multiple 8 × 8 arrays to create larger switch arrays
4. Output disable allows connection of multiple devices
5. Pin-compatible with AD8110/AD8111 16 × 8 switch arrays
6. Drives 150 Ω loads
7. Excellent video performance
8. 60 MHz 0.1 dB gain flatness
9. 0.02%/0.02° differential gain/differential phase error (RL= 150 Ω)
10 .Excellent ESD rating: exceeds 4000 V human body model
