GENERAL DESCRIPTION  
The AD8106 and AD8107 are high speed, 16 × 5 video crosspoint  
switch matrices. They offer a −3 dB signal bandwidth greater  
than 260 MHz, and channel switch times of less than 25 ns  
with 1% settling. With −78 dB of crosstalk and 97 dB isolation  
(@ 5 MHz), the AD8106/AD8107 are useful in many high speed  
applications. The differential gain and differential phase of  
greater than 0.02% and 0.02° respectively, along with 0.1 dB  
flatness out to 60 MHz, make the AD8106/AD8107 ideal for  
video signal switching.  
The AD8106 and AD8107 include five independent output  
buffers that can be placed into a high impedance state for parallel-  
ing crosspoint outputs, preventing off channels from loading the  
output bus. The AD8106 has a gain of 1, while the AD8107  
offers a gain of 2. Both operate on voltage supplies of 5 V while  
consuming only 30 mA of idle current. The channel switching is  
performed via a parallel control, allowing updating of an  
individual output without reprogramming the entire array.  
The AD8106/AD8107 are offered in an 80-lead LQFP and are  
available over the extended industrial temperature range of  
−40°C to +85°C.
