 DA-HDSDI is a multi bit-rate distribution amplifier module providing high performance 

media distribution for various signal formats from 19.4Mbps up to 1485Mbps. The unit can be configured 
to do cable equalising and reclocking of SMPTE 292M and SMPTE 259M signal formats. 
 
The input typically provides an automatic cable equaliser for up to 100 metres of cable (Belden 1694A at 
1485Mbps) with 6 re-clocked outputs. The DA-HDSDI will detect HD and SD rates and automatically 
switch to correct output slew-rate. The re-clocker supports the bit-rates; 143, 177, 270, 360, 540 and 
1485Mbps. For other rates, the re-clocker automatically switches to bypass mode, and the DA-HDSDI 
will work as a non-reclocking distribution amplifier with cable equaliser. The DA-HDSDI also has a 
special DVB-ASI mode, enabling all possible rates including empty transport streams with only K28.5 
padding packets. 3 of the outputs are non-inverting and suitable for DVB-ASI. 
 
The DA-HDSDI is designed for all distribution purposes in studio, duplication and Broadcast 
applications.
