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
slew-rate. 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.

The DA-3GHD-8-PL/DA-3GHD-8 supports a number of different formats. The correct
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.
Figure 2: DA-3GHD-8-PL/DA-3GHD-8 module layout
DIP switch configuration must be set according to Table 1:
Table 1: DA-3GHD-8-PL/DA-3GHD-8 DIP switches

3.1 Configuration Examples
Typical configurations for DA-3GHD-8-PL/DA-3GHD-8:
Figure 3: Default all off; Gyda controls the card
Figure 4: DIP control; Equalizing and reclocking turned on
Figure 5: Same as above, but if the input signal is something else than the supported bit-
rates, the reclocker will automatically enter bypass mode

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
SDI-signal 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.

5 Operation
The status of the module can be easily monitored visually by LED’s at the front of the
module. The LED’s are visible through the front panel as shown in Figure 10.
