AD8116: 200 MHz, 16 × 16 Buffered Video Crosspoint Switch
The AD8116 is a high speed 16 × 16 video crosspoint switch matrix. It offers a -3 dB signal bandwidth greater than 200 MHz and channel switch times of 50 ns with 0.1% settling. With -60 dB of crosstalk and -105 dB of isolation (@ 10 MHz), the AD8116 is useful in many high speed applications. The differential gain and differential phase errors of better than 0.01% and 0.01°, respectively, along with 0.1 dB flatness out to 60 MHz make the AD8116 ideal for video signal switching.
The AD8116 includes 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. It operates on voltage supplies of ±5 V while consuming only 80 mA of idle current. The channel switching is performed via a serial digital control that can accommodate "daisy chaining" of several devices.
The AD8116 is packaged in a 128-lead LQFP package occupying only 0.36 square inches, and is specified over the commercial temperature range of 0°C to +70°C.
An evaluation board is available for this product and may be ordered using the following product number: AD8116-EB. Schematic and layout for this evaluation board is contained in the product datasheet.
