DA-3GHD-8-MkII Rev. A
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.
