PRODUCT DESCRIPTION

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 60 ns with 0.1% settling. With –70 dB

of crosstalk and –105 dB of isolation (@ 5 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 90 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 occupy-

ing only 0.36 square inches, and is specified over the commer-

cial temperature range of 0

°C to +70°C.

*Patent Pending.
