FEATURES
16 × 16 high speed nonblocking switch arrays
AD8114; G = 1
AD8115; G = 2
Serial or parallel programming of switch array
Serial data out allows daisy-chaining of multiple
16 × 16 arrays to create larger switch arrays
High impedance output disable allows connection of
multiple devices without loading the output bus
For smaller arrays see the AD8108/AD8109 (8 × 8) or
AD8110/AD8111 (16× 8) switch arrays

GENERAL DESCRIPTION
The AD8114/AD81151 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 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.
