1 Product overview
The Flashlink DA-3GHD-8-PL and DA-3GHD-8 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 292 and SMPTE 259M signal formats.
Both modules provide 8 reclocked non-inverting outputs, and the DA-3GHD-8-PL also
provides a passive loop-through output. The passive loop-through output facilitates
distribution of the source signal to multiple cards without corruption due to powerdown or
removal of cards. The passive loop-through output must be terminated into 75 ohm, either by
connecting it to a subsequent DA-3GHD-8-PL, or by attaching a 75 ohm BNC terminator.
Both modules will detect HD and SD rates and automatically switch to correct output slewrate. The reclocker supports the bit-rates 270Mbps, 1483.5Mbps, 1485Mbps, 2967Mbps and
2970Mbps. For other rates the reclocker can automatically switch to bypass mode and the
DA-3GHD-8-PL/DA-3GHD-8 will work as a non-reclocking distribution amplifier with cable
equalizer. The DA-3GHD-8-PL/DA-3GHD-8 also supports reclocking of DVB-ASI at
270Mbps, enabling all possible rates including empty transport streams with only K28.5
padding packets. All 8 outputs (and the passive loop-through output) are non-inverting and
suitable for DVB-ASI.
The DA-3GHD-8-PL/DA-3GHD-8 is designed for all distribution purposes in studio,
duplication and Broadcast applications.

configuration can either be set with a DIP switch or with GYDA Control System. The layout of
DA-3GHD-8-PL/DA-3GHD-8 is shown in the drawing below with the DIP switch to the upper
left position.

4 Connections
Both module versions have a dedicated connector backplane which is mounted at the rear of
the sub-rack. The backplane layout is shown in Figure 6.
Due to signal performance discrepancies in slot 1 (leftmost position), slot 1 may
not be used with this product for 3G-SDI.
HD, SD and ASI meets is not affected and meets their respective performance
specifications.
Figure 6: Layout of the backplanes DA-3GHD-8-PL-C1 and DA-3GHD-8-C1.
The electrical input signal is connected to the IN BNC. On the -PL version the signal is then
passively looped to the LOOP-OUT BNC. The LOOP-OUT BNC must not be left open, if it is
not connected to another DA-3GHD-8-PL-C1 backplane, it must be equipped with a good
quality 75ohm termination. All OUT1 to OUT8 BNC’s provides non-inverted signals and can
be used for all formats, included DVB-ASI. Unused outputs should be terminated with
75ohm.
Note: In an application with two or three distribution cards looped together, the source SDIsignal will travel through several BCN connector interconnects. It is therefore very important
that those connectors are of good quality and specified for the bitrate used. Only new and
fresh interconnection equipment should be used. This is especially important to 3G-SDI.
