AD8114

    The AD8114/AD8115 are high speed 16 *16 video crosspoint switch matrices. They offer a 3 dB signal bandwidth greate  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 AD8114/AD8115 are 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  back-terminated load, make the AD8114/AD8115 ideal for all types of signal switching.

    The AD8114 /AD8115 include 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. The AD8114 has a gain of +1, while the AD8115 offers a gain of +2. They operate on voltage supplies of ±5 V while consuming only 70 mA of idle current. The channel switching is performed via a serial digital control (which can accommo date"daisy chaining" of several devices) or via a parallel cont allowing updating of an individual output without reprogramming the entire array.

    The AD8114/AD8115 is packaged in 100-lead LQFP package and is available over the extended industrial temperature range of -40 to +85.
