1 Product overview
The Flashlink DA-3GHD is a multi bit-rate distribution amplifier module providing high
performance media distribution for various signal formats from 19.4Mbps up to 2970Mbps.
The unit can be configured to do cable equalizing and reclocking of SMPTE 424M, SMPTE
292M and SMPTE 259M signal formats.
The input typically provides an automatic cable equalizer for up to 70 meters of cable
(Belden 1694A at 2970Mbps) with 8 re-clocked outputs. The DA-3GHD will detect HD and
SD rates and automatically switch to correct output slew-rate. The re-clocker supports the
bit-rates 270Mbps, 1483.5Mbps, 1485Mbps 2967Mbps and 2970Mbps. For other rates, the
re-clocker automatically switches to bypass mode, and the DA-3GHD will work as a non-
reclocking distribution amplifier with cable equalizer. The DA-3GHD also supports reclocking
of DVB-ASI at 270Mbps; enabling all possible rates including empty transport streams with
only K28.5 padding packets. 4 of the outputs are non-inverting and suitable for DVB-ASI.
The DA-3GHD is designed for all distribution purposes in studio, duplication and Broadcast
applications.

3 Configuration
The DA-3GHD 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-3GHD is shown
in the drawing below with the DIP switch to the upper left position.
Figure 2: DA-3GHD module layout
DIP switch configuration must be set according to the table below:

4 Connections
The DA-3GHD has a dedicated connector module: DA-3GHD-C1. This module is mounted at
the rear of the sub-rack. The module is shown in Figure 2.
Figure 6: Overview of the DA-3GHD-C1 connector module
The electrical input signal is connected to the IN BNC and the electrical outputs are
connected to the O1 to O8 BNCs.
Please note that O2, O4, O7 and O8 have inverted signals, so DVB-ASI cannot
be used on these outputs.
The dashes above the inverted signals are only printed in the manual; they are
not printed on the backplanes.
Unused outputs should be terminated with 75 ohm.

5 Operation
The status of the module can be easily monitored visually by the LEDs at the front of the
module. The LEDs are visible through the front panel as shown in Figure 7 below.
