GENERAL 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 (at 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.
The AD8108 and AD8109 include eight independent output
buffers that can be placed into a high impedance state for paral-
leling crosspoint outputs so that off channels do not load the
output bus. The AD8108 has a gain of 1, while the AD8109
offers a gain of 2. They operate on voltage supplies of ±5 V
while consuming only 45 mA of idle current. The channel
switching is performed via a serial digital control (which can
accommodate daisy-chaining of several devices) or via a parallel
control allowing updating of an individual output without
reprogramming the entire array.
The AD8108/AD8109 is packaged in an 80-lead LQFP and is
available over the extended industrial temperature range of
−40°C to +85°C.
