8949MDA-CXF and
8949MDA-SXF Modules
Introduction
The 8949MDA-CXF or 8949MDA-SXF module performs HD/SD equaliza-
tion and reclocking for distribution of SD/HD signals. It also provides four
dedicated downscaled electrical outputs for viewing the input video in
SD-SDI format (with the 8949MDA-SXF module) or composite format
(with the 8949MDA-CXF module), with aspect ratio controls for down-
scaled HD video on both models.
The 8949MDA-CXF module will distribute the original SD-SDI or HD-SDI
input signal on four dedicated electrical outputs as well as up to two
optional fiber optic outputs. The input signal from one electrical input or
one of two optional fiber optic inputs is downscaled to composite video
and distributed from four dedicated electrical outputs. Controls are pro-
vided for setting the aspect ratio of downscaled HD video for the desired
monitor viewing. A color bars test signal may be enabled and a control is
provided for enabling or disabling setup on NTSC outputs.
The 8949MDA-SXF module will distribute the original SD-SDI or HD-SDI
input signal on four dedicated electrical outputs as well as up to two
optional fiber optic outputs. The input signal from one electrical input or
one of two optional fiber optic inputs is downscaled to SD-SDI video and
distributed from four dedicated electrical outputs. Only the EDH CRC
packet data from the original video input is included in the downscaled
output signal. Controls are provided for setting the aspect ratio of down-
scaled HD video for the desired monitor viewing.
The aspect ratio controls include Anamorphic, Letterbox, 4x3 Center Cut,
or 14x9 Center Cut. Aspect ratio controls are only available when an HD
input signal is being downscaled.
Fiber optic interfaces can be added by ordering one of three types of
optional SFP Fiber optic submodule kits to add two fiber inputs (Dual
Receiver), two fiber outputs (Dual Transmitter), or one fiber input and one
fiber output (Transceiver). The optional SFP strap-mount optical sub-
module device is mounted on the module circuit board and must be
ordered separately. See
Table 2 on page 16 for submodule types.
