USA
FCC 47 Part 15
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to the 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 environment. This equipment generates, uses, and can radiate

Getting Started
Most CardModules are installed into the rack frames and system tested in the factory. If
this is an upgrade part or service exchange item then the module is supplied in a padded
cardboard carton which includes the CardModule, rear connection plate and mounting
screws.
Packaging
The shipping carton and packaging materials provide protection for the module during
transit. Please retain the shipping cartons in case subsequent shipping of the product
becomes necessary. Do not remove the module from its protective static bag unless
observing adequate ESD precautions. Please see below.
ESD Warning
C DX 5624 Reference Manual. Rev 2.0
This product is static sensitive. Please use caution and use preventative measures to
prevent static discharge or damage could result to module.
Preventing ESD Damage
Electrostatic discharge (ESD) damage occurs when electronic assemblies or the
components are improperly handled and can result in complete or intermittent failure.
Do not handle the module unless using an ESD-preventative wrist strap and ensure that
it makes good skin contact. Connect the strap to any solid grounding source such as any
exposed metal on the rack chassis or any other unpainted metal surface.
Caution
Periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 Megohms.

Product Description
The C DX 5624 is a high quality multi-format down converter providing down converted
digital and analog video outputs + analog and digital audio outputs.
Input Formats
The module has one multi-format serial digital input with automatic input detection. The
module will detect the following input standards and configure the input stage
automatically for operation in the connected format.
SDTV Formats HDTV Formats
525 / 59.94Hz 1080i / 59.94Hz
625 / 50Hz 1080i / 60Hz
1080i / 50Hz
720P / 59.94Hz
720P / 60Hz
720P / 50Hz
Output Formats
The module provides analog and digital video outputs. The analog video outputs are
SDTV only and the available 3 BNC connections can be configured to provide the
following analog video outputs.
3 x CVBS (composite) or
1 x YC (S-VHS) + 1 x CVBS (composite) or
1 x YUV or
1 x RGB (for HW Revision 03 only, older boards do not support this)
Two serial digital outputs are also provided which can be configured to provide 2 x digital
down converted outputs or 2 x re-clocked copies of the input signal (1>2 distribution
amplifier)
C DX 5624 Reference Manual. Rev 2.0
Conversion Modes
HDTV Inputs > Down Conversion
With a compatible HD source connected the module only supports down conversion
between divisible frame rates. For example If a frame rate of 59.94Hz is connected to the
input then the module can only output a down converted 59.94Hz output. This module will
not function as standards converter.
Please refer to the table below which shows compatible conversion modes
Input Signal Converted Output Notes
1080i / 50Hz 625 / 50Hz
1080i / 59.94Hz 525 / 59.94Hz
1080i / 60Hz 525 / 59.94Hz 59.94Hz output will drop frame
720P / 50Hz 625 / 50Hz
720P / 59.94Hz 525 / 59.94Hz
720P / 60Hz 525 / 59.94Hz 59.94Hz output will drop frame
Note. It is possible to convert between 60Hz and 59.94Hz. The resulting
cumulative error will result in dropped frames on the converted outputs.

C DX 5624 Reference Manual. Rev 2.0
SDTV Inputs
When a SDTV input is detected the module functions as a D/A converter + distribution
amplifier providing analog and digital outputs of the connected SDTV input signal.
Aspect Ratios
The module supports three aspect ratio conversion modes which can be user selected
using the local controls or preset with the optional control system.
Letterbox
This takes the 16:9 aspect ratio of the input HD signal and fits it into the 4:3 SD aspect
ratio screen with black bars at the top and bottom of the image.
Center Cut
This mode cuts the center portion of the 16:9 input signal and fills the 4:3 SD aspect ratio
screen.
Stretch to Fill
This mode takes the 16:9 input signal and distorts (vertically stretches) the image to fit
the available 4:3 SD aspect ratio space.

C DX 5624 Reference Manual. Rev 2.0
Video Processing
Note. All digital signal processing and D/A conversion is 10 bit.
Video Proc Amp
A basic video proc amp is provided for video adjustments. This provides for adjustable Y
Gain / U Gain / V Gain / Black Level / Sharpness and Hue
Note. Proc amp functions are preset to null. These parameters are adjustable via
the local controls or central control system. Please refer to page 18 for illustrations
of the available GUI controls
Aperture Correction and Color Space Conversion
Adjustable horizontal aperture correction is provided as well as selectable 709 > 601
color space (gamut) conversion. Color space conversion can be set to convert or
transparent modes. In transparent mode the color space is passed from the input to the
output.
Note. Horizontal Aperture correction is factory preset for a flat frequency response
on the SDTV outputs. (The down conversion filtering process results in a slight roll
off in high frequencies). The amount of aperture correction applied is user
adjustable via the local controls or via the central control system. Please refer to
page 18 for illustrations of the available GUI controls.
All module settings are automatically stored in internal flash ram and will survive power
cycles and long term storage.
Note. Settings will be written to flash RAM automatically after 10 seconds with no
activity. This can be observed by the alarm LED flashing yellow three times. If power
is removed before the settings have been stored the module will revert back to the
previous settings when powered up
Audio Processing
The module provides full audio support and will de-embed the complete audio payload
(8xAES) from the incoming SDI signal. This audio is delayed to match the video
processing delay (1 frame) and then re-embedded into the digital down converted
outputs.
Four of the de-embedded AES signals can be selected and output as external digital AES
signals (balanced AES3 signals on the SubD connector). Two additional AES signals can
be selected and output as balanced analog outputs via high quality 24 bit Audio D/A
converters. Full scale ranging, adjustable gain and de-emphasis is provided for each
analog audio output. Balanced analog audio outputs are provided on the integrated 25
pin SubD connector.
DolbyE
If the incoming SDI signal has an encoded DolbyE stream this will be de-embedded,
delayed one frame and re-embedded into the same channels on the down converted SDI
outputs. Providing the Dolby “Guard Band” was timed correctly on the input then the SDI
outputs will have the correct DolbyE audio timing and guard band timing will be
preserved.

Test Patterns
The module contains a selection of video test patterns which can be used for testing and
fault finding. Patterns provided are 75% Colorbars, 75% Colorbars over Red, Full Field
Black, Pathological PLL/EQ and Full field Blue (blue screen). Test patterns are provided
on the analog and Digital video outputs in the selected format. If configured to pass the
input HDTV to the digital outputs then both a Digital HD Test patterns and an Analog
SDTV patterns are provided.
By pre-selecting the input format (with no input connected) the Module can be used as a
stand alone multi-format Test Pattern Generator.
