Product Overview
The KD-CTCA3 ClearVideo3 is the world’s smallest
video adapter on the market to “glue” your
Component Video (YPrPb) devices to VGA monitors
and projectors. ClearVideo3 is the ideal choice to
drive your VGA displays from Component Video
sources like your progressive DVD player, video
KD-CTCA3
Model KD-CTCA3

game (like Xbox and Game Cube), or HDTV Set Top
Boxes. ClearVideo3 works with most* video formats,
like 480p, 720p, 1080i/540p, NTSC, PAL, interlaced
or progressive. With your Key Digital cost-effective
ClearVideo3 product, you get crystal-clear processing and you can drive your VGA monitor with cable
lengths up to 50 feet..
OPERATING INSTRUCTIONS

*NOTE: To drive VGA monitors, the source video format must be above a 31 kHz scanning rate. The
user should note that a typical VGA monitor
therefore will NOT display formats like 480i/60 and
576i/50 that are in the range of 15.7 kHz.

Why do you need a Video Adapter?
The video industry has produced many different
products to process, switch, and distribute your
video. In many instances, the video input or output
formats of these products are not compatible. For
example, you may have an application where you
would like your video game with Component Video
(YPrPb) out to drive your VGA (RGBHV) display.
OPERATING INSTRUCTIONS

What do you do? One less-palatable option is to
purchase all new equipment that is totally
compatible, which is a significant investment and
limits you for the future to ever consider equipment
that does not conform to the standard you purchased. At Key Digital, we have a better solution for
you. We have designed economical, high-quality
KD-CTCA3

video adapters, which “glue” your components that
may have been designed to diverging standards:
•
KD-CTCA3 ClearVideo3: Component
Video (YPrPb) to VGA adapter, and more
• KD-CTCA3 ClearColor3: VGA to
Component Video adapter, and more

ators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9)Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding
type plug has two blades and a third grounding
prong. The wide blade or the third prong are
provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for

replacement of the obsolete outlet.
10)Protect the power cord from being walked on or
pinched particularly at plugs, convenience
receptacles, and the point where they exit from the
apparatus.
11)Only use attachments/accessories specified by
the manufacturer.
12Use only with the cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with the

apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid
injury from tip-over.
13)Unplug this apparatus during lightning storms or
when unused for long periods of time.

Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.

QUICK SET-UP
Connecting and using your KD-CTCA3 ClearVideo3 is
a simple process.
NOTE: Do not attempt to connect power to the unit
until you have completed all Steps 1 – 4.
STEP 1:
Determine your configuration
KD-CTCA3
Model KD-CTCA3

requirements. The primary function of the
KD-CTCA3 ClearVideo3 is to convert your Component
Video (YPrPb) signal to VGA (RGB). The unit
automatically adjusts to the input scan format.
There are added bonuses that let you also
simultaneously drive your Component Video
monitor, or even automatically pass-through a VGA
source (like from your PC) to the VGA output when
Component Video is Typical configuration with
ACTIVE YPbPr Component
QUICK SET-UP

Input always passing through to the YPbPr loopthrough output, and automatically converted to VGA.
This configuration allows your Component Video
source to SIMULTANEOUSLY drive your Component
Video monitor and VGA monitor.
inactive, as demonstrated in the figures below.
Typical configuration with INACTIVE YPbPr
QUICK SET-UP

Component Input, and “Auxiliary” VGA Input passed
on to the VGA output. This configuration allows
your VGA source to be connected to the VGA monitor in cases where the Component Video source is
INACTIVE – perfect for PC applications.
QUICK SET-UP

STEP 2: Make your Input Connections:
• One Component Video (YPrPb) input on three RCA
female jacks
• If desired, one “auto switching” VGA (RGBHV) input
will drive the RGBHV output when Component Video
input has no sync on “Y”
STEP 3: Make your Output Connections:
• One VGA Video (RGBHV) output on DB15 connector
KD-CTCA3
Model KD-CTCA3

that can drive two monitors with equal cable lengths
up to 50 feet
• If desired, one Component Video (YPrPb)
always-active pass-through output on three RCA
female jacks (be sure to terminate this output at
the end of the runs)
STEP 4: Configure the Sync Output Select Switches
(adjacent to the Component Video input connectors)
to suit your application. H&V polarity out for
Component Video to RGBHV conversion is always
QUICK SET-UP

NEGATIVE polarity. H&V polarity out for the case
when the auxiliary VGA input signal (like from a PC)
is switched to the VGA output is always the SAME as
the polarity of H&V on the input VGA signal.
Select between H and V drive sync or Composite
Sync with Switch 1:
• Switch 1 ON (up): H and V drive VGA out (typical
mode, RGBHV)
• Switch 1 OFF (down): Composite Sync out on H,
KD-CTCA3
Model KD-CTCA3

and V (RGBHcV)
Select between H and V drive sync or Sync-on-Green
with Switch 2:
• Switch 2 ON (up): H and V drive VGA out (typical
mode, RGBHV)
• Switch 2 OFF (down): Sync-on-Green mode
(RGsB)
STEP 5: Apply power to the unit:
QUICK SET-UP

• Use ONLY the external wall-plug power supply
provided with your unit, +5 Volts @ 03.Amps, 100240 VAC, 50-60 Hz
• Connect the 1/8” mini-plug external power supply
connector to your unit, and plug the power supply
into a power outlet
• The green Power-on LED (adjacent to the external
power supply connector) should be ON
STEP 6: Operation of your unit:
KD-CTCA3
Model KD-CTCA3

• Your Component Video source should now drive
your VGA display and is also available as an active
Component Video pass-through
• The red LED (adjacent to the external power
supply connector) indicates sync detected on the
Y Component Video input when LED is ON
• If you also have a VGA input connected to the unit,
it should be passed to the VGA output when the red
LED is OFF, indicating the Component Video source is
inactive (Auto-switch feature)
