FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The SDA-1112 is a reclocked serial digital video
distribution amplifier supporting a wide variety of
compressed and uncompressed serial digital video
signals. The SDA-1112 provides 9 reclocked
outputs with automatic equalization for up to 350
meters of cable (Belden 1694A). The amplifier also
offers signal presence detection and remote
reporting. The SDA-1112 includes reclocking,
providing an additional level of signal integrity in
longcable length applications The SDA-1112
supports DVB-ASI 270 Mbps compressed bit
streams as well as serial digital video at bit rates of
143, 177, 270, 360 and 540 Mbps. The SDA-1112
is designed to be used in a DENSITÉ frame. A
single (for 4 outputs) or double (for 9 outputs) rear
connector panel is required.
This card operates with the MSB-1121 Monitoring
Switching Bridge which allows the output of any
module in the Densité frame to be monitored.
Multiple MSB equipped frames may be cascaded
to form a large monitoring bus, eliminating the
need for dedicated monitoring routers.

UNPACKING
Make sure the following items have been shipped
with your SDA-1112. If any of the following items are
missing, contact your distributor or Miranda
Technologies Inc.
* SDA-1112 Reclocked Digital Video DA
* SDA-1112 rear panel (single or double)
INSTALLATION
The SDA-1112 must be mounted in a DENSITÉ
frame. The installation includes both the SDA-1112
module, and the rear panel module. It is not
necessary to switch off the power from these frames
when installing or removing the SDA-1112.
Detailed instructions for installing cards and their
associated rear panels in the Densité frame are given
in the Densité Frame manual. Specific points to note
for the SDA-1112 are the following.
Rear panel installation
The SDA-1112 has nine outputs, and making these
available on BNC connectors at the rear of the frame
requires a double-width rear panel. Should the
intended use require a smaller number of outputs, a
single-width rear panel with four BNC output
connectors is also available.
In the case where a double rear panel has been
installed, the module must be installed in the right-
most of the two slots covered by the panel in order to
function. Should it be installed in the wrong slot, the
front panel LED will flash red (see OPERATION for a
discussion of the LED functionality). Move the card to
the other slot for correct operation. No damage will
result to the card should this occur.
OPERATION
Overview
Distribution amplifiers require a minimal operator
interface. The SDA-1112 is equipped with an on-
board LED status indicator, mounted on the front
edge of the card so as to be visible from the front of
the card frame, even when the frame door is closed.
The functionality of this status monitor is described
below.
The DENSITÉ frame incorporates a central controller
card, located in the center of the frame, which is
equipped with an LCD display. The card handles
error reporting and remote control for all cards
installed in the frame. The display shows the error

status of any card in the frame whose SELECT
button has been pushed.
The SDA-1112 is also equipped with the remote
reporting and control capabilities of the DENSITÉ
series. Fault reporting is carried out on a frame-wide
basis. There is no individual rear-panel access to the
fault and status reporting port of the SDA-1112.
Interfacing to the outside world is handled by the
frame’s contoller card. The fault reporting protocol is
standardized across the DENSITÉ series of modules.
The communications protocol and functionality are
described elsewhere.
Status Monitor LED
The status monitor LED is located on the front card-
edge of the SDA-1112 module, and is visible through
the front access door of the DENSITÉ frame.
This is a multi-color LED, which indicates module
status by color, and by flashing/steady illumination.
The SDA-1112 uses three of the available modes.
They are summarized in the following table. The
table also indicates that a serial report will be filed for
the indicated error condition, through the remote
reporting protocol of the DENSITÉ frame if it is
operative.

NOTE: A “Flashing Yellow” Status LED indicates that
the SELECT button on the front panel has been
pushed, and the card is being accessed via the
communications protocol. The LED color
assignments for the various error conditions can be
reconfigured by the user.
User Interface
Push the SELECT button on the front edge of the
SDA-1112 to see a report of the current error status
on the DENSITÉ frame’s controller card display. The
SDA-1112 has four possible status messages, as
indicated in the following figure:
STATUS
ERROR NO REAR
OK
ERROR NO SIGNAL
ERROR NO LOCK
Pushing the SELECT button will cause the on-card
STATUS LED to flash yellow, and the card identifi-
cation and the current error message will be shown
on the controller card’s display. The STATUS LED
will revert to it’s normal state upon a second push of
the button, or after a short delay otherwise.
