C DX 5624 Reference Manual. Rev 2.0
Product Description
The C DX 5624 is a high quality multi-format down converter providing down converted
digital and analog video o 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)
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

525 / 59.94Hz
1080i / 60Hz
525 / 59.94Hz
59.94Hz output will drop frame

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.
