The Grablink Avenue is an ultra-fast
PCI frame grabber for line-scan or area-scan digital
Camera Link cameras. Grablink Avenue is a high-performance
64-bit, 66 MHz PCI bus board acquiring images
from one camera in the Camera Link Base configuration.
This board acquires the 24-bit data, with any
tap structure, at the maximum speed of 85 MHz
allowing to be interfaced to the fastest cameras.
With line-scan cameras, the Grablink Avenue guarantees
a constant sensitivity of the image regardless
of the web speed variation, thanks to ADR*, a
unique patented downweb resampler.
- Base configuration -up to 24 bits at 85 MHz-
- Enhanced support of line-scan cameras, ADR
Technology*
- Full support of area-scan cameras
- (asynchronous reset and exposure control)
- 9 various external and internal I/O lines
- 32-Mbyte on board memory
- 64-bit, 66 MHz PCI bus, 3V/5V signaling

ADR Technology™* - Advanced Downweb
Resampling
 In
many applications, a line-scan camera has to be operated
at a constant cycling rate in order to maintain a constant
sensitivity. Grablink Avenue implements ADR*, a unique
downweb resampling feature, yielding a defined aspect
ratio irrespective of web speed variations, even without
an electronic shutter on the camera.
A built-in rate converter accommodates an off-the-shelf
motion encoder to control the line acquisition process,
enabling any programmable aspect ratio, including perfect
square pixels. ADR* makes the most of the line-scan
camera, as the sensitivity is not impaired by the shuttering.
More About ADR Technology
64-bit 66 MHz PCI bus
The 64-bit, 66 MHz PCI bus of the Avenue is compatible
with all the conventional PCI slots of a PC: from 32-bit,
33 MHz -5V- to 64-bit, 66 MHz -3 V-. For more information
the "PCI Variation Application Note" is available
on the download area.
In addition, Direct Memory Access for each camera connected
and PCI bus mastering are offered.
Nine various external and internal I/O
lines
The Grablink Avenue is fitted with a male HD26 external
connector and a 26-pin internal header. All nine I/O
connections are available both from the outside of the
PC enclosure or directly from the PCB. System components
such as trigger, strobe or motion encoder benefit from
different types of interface:
- One opto-isolated output for the safe control of
external equipment
- Two differential, including LVDS compatibility,
input lines for high-speed flexible control of the
acquisition
- Two isolated I/O lines and associated power supply
compatible with the other Grablink boards
- Four enhanced TTL I/O lines used, for instance,
for interface with the user application
