General Description
1.1 Features
The Texas Instruments MC-1000WU-20A camera features the Texas
Instruments TC215 solid-state monochrome charge-coupled-device (CCD)
image sensor. The camera is for vision system applications requiring high-
resolution and high-sensitivity operation. The camera features include:
- TV frame rate, 15 Hz
- High sensitivity, 0.35 lux typical
- 12 m m square pixel
- TI-Virtual Phase CCD technology
- High blue response
- High near-IR response
- Electron-hole recombination antiblooming
- 100% optical fill factor

General Description
1.2 Introduction
TheMC-1000WU-20A isoneof aseriesof high-resolutionvideocameras that
employs TI’s mega-pixel CCD image sensors. The cameras are intended for
scientific and industrial imaging applications where image data processing is
required.
The MC-1000WU-20A camera employs the TI TC215 full-frame CCD image
sensor, which features 1,017,000 active photosites, resulting in a very-high-
resolution image. The TC215 sensor provides high sensitivity and good
spectral response as a result of the TI patented Virtual Phase technology.
TheTC215 sensor measures 17.2mm diagonally and features12- m msquare
pixels. The square pixels permit symmetrical image measurement in both the
X and Y axis. The photosite has a 100% fill factor and is responsive to wave-
lengths in the ultraviolet through the visible and into the near-infrared spectral
regions. The camera outputs composite analog video at a 20-mega-pixel per
second data rate. Two operating options can be selected - a normal operating
modeand a programmable shuttermode.In addition, the cameraprovidesfor
auto-iris control.
A mechanical shutter or strobe light is recommended for most
MC-1000WU-20Acameraapplications.Theshutteroperationissynchronized
to the camera by supplying an external shutter command signal. The shutter
may operate from a minimum integration time of 1/2500 second to 1/125
second or 10 frames/s maximum. Figure 1–1 shows the camera interface
options and mode selection.

(excluding lens) by 68.0 mm high by 68.0 mm wide. It is self-containedexcept
for power supply and monitor. The camera weighs 2.09 pounds.
The MC-1000WU-20A offers a standard TV C-mount lens attachment with an
adjustable lens locking ring to allow precise adjustment of the lens back focal
length. A variety of lenses or mechanical shutters may be used.

General Description
1.5 Equipment Required But Not Supplied
TheMC-1000WU-20A camerausesthe full-frameTC215CCD imagesensor.
This full-frame format sensor requires a mechanical shutter or an electronic
light strobe to prevent image smear. The shutter or strobe light allows scene
informationtobecapturedduringeithertheopentimeoftheshutteroron-time
of the strobe light. The transfer or read-out of the captured scene information
is performed during the closed time of the shutter or off-time of the strobe.
Once the shutter or strobe light is chosen, an appropriate lens may also be
selected.
The MC-1000WU-20A camera supplies analog video at either a 15-Hz frame
rate in the TV mode or a 10-Hz frame rate in the shutter mode and can be
displayed directly to a video monitor capable of those frame rates. However,
many applications require the addition of a custom or commercially available
frame-buffer or other video processing equipment. This hardware will enable
the user to capture and digitally process the scene information. The
MC-1000WU-20A is presently supported by several manufacturers of video
processing hardware and software systems. Most manufacturers have
application notes available describing the interface required.

2.2 Interface Circuit
The input interface circuit of VD, HD, and MCK shown in Figure 2–1, consists
of one SN75124 input gate pulled up through a 4.7-k W resistor to 5 Vdc and
pulled down to ground through an optional 100- W resistor. The optional pull
down is selected by jumpers JP1 (MCK), JP2 (HD), and JP3 (VD).
