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.
