1 Product overview
The Flashlink DA-3GHD-8-MkII 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.
The product provides 8 reclocked non-inverting outputs. It will detect 3G/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 DA-3GHD-8-MkII will work as a non-reclocking
distribution amplifier with cable equalization. DA-3GHD-8 also supports reclocking of DVBASI at 270Mbps, enabling all possible rates including empty transport streams with only
K28.5 padding packets. All 8 outputs are non-inverting and suitable for DVB-ASI.
DA-3GHD-8-MkII is designed for all distribution purposes in studio, duplication and Broadcast
applications.

3 Configuration
The 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 the main module is
shown in the drawing below with the DIP switch to the upper left position.
Figure 2: DA-3GHD-8-MkII module layout
DIP switch configuration must be set according to Table 1:
All DIP switches are off when pointing towards the release handle.

3.1 Configuration Examples
Typical configurations for DA-3GHD-8-mkII:
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
The backplane layout is shown in Figure 6.
Figure 6: Layout of the backplane DA-3GHD-8-C1-MkII
The electrical input signal is connected to the IN BNC. All OUT1 to OUT8 BNC’s provide noninverted signals and can be used for all formats, included DVB-ASI. Unused outputs should
be terminated with 75ohm.
