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.
