1. General

The flashlink ® DA-HDSDI is a multi bit-rate distribution amplifier module providing high performance

media distribution for various signal formats from 19.4Mbps up to 1485Mbps. The unit can be configured

to do cable equalising and reclocking of SMPTE 292M and SMPTE 259M signal formats.

The input typically provides an automatic cable equaliser for up to 100 metres of cable (Belden 1694A at

1485Mbps) with 6 re-clocked outputs. The DA-HDSDI will detect HD and SD rates and automatically

switch to correct output slew-rate. The re-clocker supports the bit-rates; 143, 177, 270, 360, 540 and

1485Mbps. For other rates, the re-clocker automatically switches to bypass mode, and the DA-HDSDI

will work as a non-reclocking distribution amplifier with cable equaliser. The DA-HDSDI also has a

special DVB-ASI mode, enabling all possible rates including empty transport streams with only K28.5

padding packets. 3 of the outputs are non-inverting and suitable for DVB-ASI.

The DA-HDSDI is designed for all distribution purposes in studio, duplication and Broadcast

applications.

3. Format Configuration

The DA-HDSDI supports 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-HDSDI is shown in the drawing

below with the DIP switch to the upper left position.

Figure 2 – DA-HDSDI board layout.

DIP switch configuration must be set according to the table below:

4. Connector module

The DA-HDSDI has a dedicated connector module: DA-SDI-C1. This module is mounted at the rear of

the sub-rack. The module is shown in figure 6.

Figure 6 - Overview of the DA-SDI-C1 connector module

The electrical input signal is connected to the IN BNC and the electrical outputs are connected to the O1

to O6 BNC. Please note that O2, O4 and O6 has an inverted signal, so formats like DVB-ASI can not use

be used on these outputs.

Unused outputs should be terminated with 75 ohm.

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 7.

Electrical Maximums for GPI outputs

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 8 below.

(Text not printed on the front panel).

Figure 8 - Front panel indicator overview for DA-HDSDI

The DA-HDSDI has 4 LED’s each showing a status corresponding to the GPI pinning. The position of

the different LED’s is shown in figure 8.
