1.0 Introduction to the CA-D6
1.1 Camera Highlights
•260x260 or 532Hx516V pixels, 10 µm square with 100% fill factor
•Frame transfer architecture and pixel resetno shutter required
•4 outputs at 25 MHz: frame rates to 955 or 262 frames/sec
•8 bit digital data in EIA-644 (LVDS differential) format
•Separate connectors for power, control and data
•“Snapshot” operation
•Vertical antiblooming
•Operation verified to limits set in EMC standards IEC 1000-4-2; 1995, 1000-4-3;
1995, 1000-4-4; 1995, and CISPR-22.
The CA-D6-xxxxW cameras use DALSA’s patented modular architecture. This
system of connecting circuit modules through standardized busses allows
DALSA to build a high performance modular camera using the reliability,
flexibility, and cost-effectiveness of high-volume interchangeable parts. Within
the camera, a timing board (PB-D6-X205) generates all internal timing and a
driver board (PB-D6-A198) provides bias voltages and clocks to the CCD image
sensor. Two A/D boards (PB-xxD344) process the video and an output board
(PB-xx-X733) filters the power lines.
1.2 Image Sensor
The CA-D6-xxxxW use the IA-D6 family of image sensors. Available in 260x260
and 532x516 arrays, the sensors have 10 µm square pixels with 100% fill factor.
The IA-D6 image sensors use a frame transfer architecture, providing on-chip
storage.

1.4 CCD Camera Primer
How CCD Image Sensors Work
In a CCD camera such as the CA-D6-xxxxW, a CCD image sensor converts
photons (light) into electrons (electricity). When photons hit an image sensor, an
electron is released, and the sensor adds this electric charge to the charge it has
already collected. This is called charge integration. The brighter your light
source, the more photons available for the sensor to integrate, and the smaller
the amount of time required to collect a given amount of charge.
The way photosensitive elements (pixels)
on CCD image sensors collect charge has
often been compared to buckets filling
with water. From this analogy comes the
term “full-well capacity,” meaning the
maximum charge (number of electrons) a
pixel can hold without “spilling” charge
onto adjacent pixels.
As light energy hits an array of pixels, the pixels collect charge. At certain
intervals, a frame transfer sensor such as the IA-D6 transfers its collected charge
from the active, photosensitive region to a light-shielded storage region. Then it
transfers the charge, line by line, to one or more readout registers, which feed
each pixel’s charge from the image sensor into an output node that converts the
charges into voltages.
After this transfer and
conversion, the
voltages are amplified
to become the camera’s
analog output. In
digital output cameras,
the camera’s analog-to-
digital (A/D) board
converts voltages to
digital numbers (0-255
for 8-bit cameras).
These digital numbers
are what the camera
outputs as data to a framegrabber.

DALSA’s current Databook Glossary, CCD Technology Primer, and Application Notes.

2.1 Installation Overview
In order to set up your camera, you should take these steps:
1. Decide on modes of operation—will you use USR_EN?
2. Test and connect power supplies.
3. Test and connect User Bus control signals from framegrabber.
4. Test and connect data signals output from camera.
You must also set up the other components of your system, including light
sources, framegrabbers, camera mounts, heat sinks, host computers, optics, and
so on.

Note on DB50 connectors: There are several standard ways to number the pins of DB50 connectors.
The connectors on the back of the camera use the “crimp” convention, but many shielded connectors
used to control EMI/EMC (including the Amphenol part listed here) use the “solder” convention. To help
you translate between numbering conventions, this pinout table lists both. The signals are located on the
same physical pins in both cases, but the STROBE pin is numbered 37 under the “crimp” convention and
13 under the “solder” convention.
