PRODUCT DESCRIPTION
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
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 control
allowing updating of an individual output without reprogram-
ming 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.
