EQUIPMENT NEEDED
Signal source or video pattern generator and signal analyzer
Power supplies (5 V/1 A and ±5 V/1 A)
PC running Windows XP only
Type A to Type B USB 2.0 connector (recommended)
BNC to BNC connector for inputs and outputs
SOFTWARE NEEDED
For the AD8112, use the ADV3224/ADV3225 control
software for the 16 × 8 switch array
For the AD8113, the AD8114/AD8115, and the ADV3205, use
the ADV3226/ADV3227 control software for the 16 × 16
switch array
GENERAL DESCRIPTION
The AD8112 is a low cost, 16 × 8 fully buffered crosspoint switch
matrix, and the AD8113 is a 16 × 16 fully buffered crosspoint
switch matrix. Both products operate on voltage supplies of ±12 V
for audio applications and of ±5 V for video applications, offering a
−3 dB signal bandwidth greater than 60 MHz and channel switch
times of less than 60 ns with 0.1% settling for use in both analog
and digital audio. Both the AD8112 and the AD8113 have gain
of +2.
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. The AD8114/AD8115 include 16 independent
output buffers that can be placed into a high impedance state
for paralleling crosspoint outputs to prevent off channels from
loading the output bus. The AD8114 has a gain of +1 while the
AD8115 has a gain of +2. They both operate on voltage supplies
of ±5 V while consuming only 70 mA of idle current. Channel
switching is performed via a serial digital control that can accom-
modate the daisy-chaining of several devices or via a parallel
control to allow updating of an individual output without
reprogramming the entire array.
The ADV3205 is a 16 × 16 fully buffered crosspoint switch matrix
that operates on ±5 V, making it ideal for video applications, and
has a gain of +2. The ADV3205 offers a −3 dB signal bandwidth
of 60 MHz and channel switch times of less than 60 ns with 0.1%
settling.
The AD8112, the AD8113, and the ADV3205 are available in a
100-lead LQFP over the commercial temperature range of 0°C to
70°C. Some applications of these analog crosspoint switches are
closed circuit television (CCTV) surveillance/DVR, analog/digital
audio routers, video routers (NTSC, PAL, S-video, SECAM),
multimedia systems, and video conferencing.
The AD8114/AD8115 are available in a 100-lead LQFP over the
extended industrial temperature range of −40°C to +85°C. Some
applications of these analog crosspoint switches are routing of high
speed signals including video (NTSC, PAL, S-video, SECAM,
YUV, RGB), compressed video, three-level digital video, data
communications, and telecommunications.
The AD8112, AD8113, AD8114/AD8115, and ADV3205 are all
pin-compatible with each other and are available in the same
100-lead LQFP, which can be evaluated on a single board.
This user guide provides all of the supporting documents and
software for the evaluation of the AD8112, AD8113, AD8114/
AD8115, and ADV3205. Complete specifications for the AD8112,
AD8113, AD8114/AD8115, and ADV3205 are available in the
AD8112, AD8113, AD8114/AD8115, and ADV3205 data sheets
available from Analog Devices, Inc., and should be consulted when
working with the evaluation board.
