Product Summary

The AD8115AST is a high speed 16 × 16 video crosspoint switch matrice. It offers a –3 dB signal bandwidth greater than 200 MHz and channel switch times of less than 50 ns with,1% settling. With –70 dB of crosstalk and –90 dB isolation (@ 5 MHz), the AD8115AST is useful in many high speed applications. The differential gain and differential phase of better than 0.05% and 0.05° respectively, along with 0.1 dB flatness out to 25 MHz while driving a 75 W back-terminated load, make the AD8115AST ideal for all types of signal switching. The AD8115AST includes 16 independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs so that off channels do not load the output bus.
