Description
This camera is designed with three concepts in mind: accuracy, versatility and easy
implementation.
·
The same compact mechanical design incorporates all the sensors, from 512 to
4096 pixels.
·
Atmel manages the whole chain, from the sensor to the camera. The result is a
camera able to work up to 12-bit, with a dedicated electronics offering an excellent
signal to noise ratio.
·
The programmable settings let the user work at different integration time, gain and
offset. The external clock and trigger synchronize several cameras.
Applications
Performance and reliability of this camera make it well suited for the most demanding
industrial applications, from web inspection to document scanning, from surface
inspection to metrology.

Description
Figure 1. Camera Synoptic
The CameraLink linescan is based on a two-tap linear CCD. Therefore, two analog chains pro-
cess odd and even pixel outputs of the linear sensor. The CCD signal processing
encompasses the correlated double sampling (CDS), the dark level correction (dark pixel
clamping), the gain (PGA) and offset correction and finally the analog to digital conversion on
12-bit.
Note:
PGA stands for Programmable Gain Array.
The camera is powered by a single DC power supply from 12V to 24V.
The functional interface (data and control) is provided with the CameraLink interface. The
camera uses the base configuration of Cameralink standard.
Note:
DVAL = 1 and FVAL = 0
The data can be delivered either on two channels or on a single multiplexed channel. The data
format can be configured in 8-, 10- or 12-bit.
The camera can be used with external triggers (TRIG1 and TRIG2 signals) in different trigger
modes (see "Synchronization Mode" on page 6). The camera can be also clocked externally,
allowing system synchronization and/or multi-camera synchronization.
The camera configuration and settings are performed via a serial line.
This interface is used for:
·
Gain, offset setting.
·
Dynamic range, data rate setting.
·
Trigger mode setting: free run or external trigger modes.
·
Integration time setting: in free running and external trigger mode.

Standard
Conformity
The cameras have been tested in the following conditions:
·
Shielded power supply cable.
·
CameraLink
TM
data transfer cable ref. 14B26-SZLB-500-OLC (3M).
·
Linear AC-DC power supply.
·
Atmel recommends using the same configuration to ensure the compliance with the
following standards.
CE Conformity
AViiVA Cameras comply with the requirements of the EMC (European) directive 89/336/CEE
(EN 50081-2, EN 61000-6-2).
FCC Conformity
AViiVA Cameras comply with Part 15 of FCC rules.
Operation is subject to the following two conditions:
·
This device may not cause harmful interference, and
·
This device must accept any interference received, including interference that may cause
undesired operation.
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial envi-
ronment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his
own expense.
Warning: Changes or modifications to this unit not expressly approved by the party responsi-
ble for compliance could void the user's authority to operate this equipment.

Command and
Control
Camera configuration is set through the serial interface. Please refer to "Serial Communica-
tion" on page 10 for the detailed protocol of the serial line.

Notes: 1. ATMEL commends to use E = 1 because of the limited EEPROM write cycles refer on page 10.
2. Camera gain (dB) = G x 0.047. A and B gain value are set in manufacturing but can be adjust if necessary.
3. Commands "H=2" and "H=4" will give 10 and 15 MHz data rate which are not compatible with CameraLink standard. Please
don't use it.
4. The pinout corresponding to this option is fully compatible with the CameraLink standard.
5. The test pattern is useful to check if the interfacing is well done. The user should see a jagged image of 256 pixels steps.
6. The offset is set in manufacturing to balance both the channels. The initial setting is about 8 (~ 130 LSB). In some cases, the
user may have to change it (for example if the ambient temperature is very high).
7. To be used for multi-camera synchronisation. Refer to Figure 6.
