DA-SDI Rev. H
1 Product overview
The Flashlink DA-SDI is a serial digital video distribution amplifier module providing
high performance media distribution for various signal formats from 1Mbps up to
540Mbps. The unit can be configured to do cable equalising and reclocking of SMPTE
259M and DVB-ASI signal formats.
The input typically provides an automatic cable equaliser for up to 300 metres of cable
(Belden 8281A at 270Mbps) with 8 re-clocked outputs. The re-clocker supports the bitrates; 143, 177, 270, 360 and 540Mbps. For other rates, the re-clocker automatically
switches to bypass mode, and the DA-SDI will work as a non-reclocking distribution
amplifier with cable equaliser. The DA-SDI also has a special DVB-ASI mode, enabling
all possible rates including empty transport streams with only K28.5 padding packets.
Outputs 1-6 are non-inverting to support DVB-ASI compatibility. Outputs 7 and 8 are
inverting.
The DA-SDI is designed for all distribution purposes in studio, duplication and
Broadcast applications.

3 Format configuration
The DA-SDI can support a number of different formats. The correct configuration can
either be set with a DIP switch or with the GYDA Control System. The layout of DA-SDI
is shown in the drawing below with the DIP switch to the upper left position.
Figure 2: DA-SDI board layout.
DIP switch configuration must be set according to the table below:
When the default setting is selected, all clock rates for SDI and DVB-ASI are
automatically configured by the module itself.

All DIP switches are off when pointing towards the release handle.

4 Connector module
The DA-SDI has two dedicated connector modules: DA-SDI-C1 and DA-SDI-C2. These
modules are mounted at the rear of the sub-rack. The modules are shown in Figure 6
and Figure 7.
Figure 6: Overview of the DA-SDI-C1 connector module.
On DA-SDI-C1 the electrical input signal is connected to the IN BNC and the electrical
outputs are connected to the O1 to O6 BNC’s. Please note that all 6 outputs are noninverted and suitable for DVB-ASI.
Unused outputs should be terminated with 75 ohm.
DA-SDI-C1 also has GPI ALARM outputs on a RJ45 connector.
nevion.com | 8
DA-SDI Rev. H
On DA-SDI-C2 the electrical input signal is connected to the IN BNC and the electrical
outputs are connected to the O1 to O8 BNC’s. Please note that outputs 1 to 6 are noninverted and suitable for DVB-ASI, while outputs 7 and 8 are inverting and cannot be
used for DVB-ASI.
Figure 7: Overview of the DA-SDI-C2 connector module.
Unused outputs should be terminated with 75 ohm.
DA-SDI-C2 does not have any GPI alarm outputs.
4.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user manual for
the sub-rack frame FR-2RU-10-2.

5 Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself, whereas the
GYDA System Controller is a separate module giving detailed information on the card
status. The functions of the GPI and the LED’s are described in sections 5.1 and 5.2.
The GYDA controller is described in a separate user manual.
5.1 GPI ALARM – Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The
GPI outputs are open collector outputs, sinking to ground when an alarm is triggered.
The GPI connector is shown in Figure 8.

Max current: 100mA

5.2 Front Panel - Status Monitoring
The status of the module can be easily monitored visually by the LED’s at the front of
the module. The LED’s are visible through the front panel as shown in Figure 9 below.
(Text not printed on the front panel).
Figure 9: Front panel indicator overview for DA-SDI.
The DA-SDI has 4 LED’s each showing a status corresponding to the GPI pinning. The
position of the different LED’s is shown in Figure 9.
