DA-SDI Rev. 6
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 bit-rates;
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:
Switch # Label Function DIP=OFF Function DIP=ON Comment
1 ARB Output muted when
reclocker not in lock Automatic Reclocker Bypass. Output never
muted
Output mute
2 EQM Equaliser forced not to
mute Automatic muting of equaliser when signal
strength is too low

3 RCL Reclocker Bypass Reclocker ON Reclocker mode
4 EQ Cable equaliser Bypass Cable equaliser ON Equaliser mode
5 ASI SDI 177Mbps Reclocker

All DIP switches are off when pointing towards the release handle.
When the default setting is selected, all clock rates for SDI and DVB-ASI are automatically
configured by the module itself.

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 non-inverted
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.

DA-SDI Rev. 6
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 non-
inverted 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.
This manual is also available from our web site: http://www.network-electronics.com/.

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.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V
