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 paralleling 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.
