The AD8114/AD8115 are high-speed 16 × 16 video crosspoint
switch matrices. They offer a –3 dB signal bandwidth greater 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 Ω 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 accommodate
“daisy chaining” of several devices) or via a parallel control
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°C to +85°C.
