DA-SDI Rev. H
1 Product overview
The Flashlink DA-SDI is a serial digital video distribution amplifier module providing
high performance media distribution for various signal formats from 1Mbps up to
540Mbps. The unit can be configured to do cable equalising and reclocking of SMPTE
259M and DVB-ASI signal formats.
The input typically provides an automatic cable equaliser for up to 300 metres of cable
(Belden 8281A at 270Mbps) with 8 re-clocked outputs. The re-clocker supports the bitrates; 143, 177, 270, 360 and 540Mbps. For other rates, the re-clocker automatically
switches to bypass mode, and the DA-SDI will work as a non-reclocking distribution
amplifier with cable equaliser. The DA-SDI also has a special DVB-ASI mode, enabling
all possible rates including empty transport streams with only K28.5 padding packets.
Outputs 1-6 are non-inverting to support DVB-ASI compatibility. Outputs 7 and 8 are
inverting.
The DA-SDI is designed for all distribution purposes in studio, duplication and
Broadcast applications.
