1 Introduction 

The DDA108A-BP is a non-reclocking serial digital video and ASI distribution amplifier 
with up to eight outputs. It has auto-equalisation for up to 250 metres of coaxial cable.  

The universal connection system allows a mixture of Crystal Vision modules in the frame.  
The modules plug in the front and the rear connectors plug in the rear. Depending on 
frame design, a hinged or removable front panel reveals LED indication of input and PSU 
status when opened. 

 

DDA108A-BP non reclocking ASI/SDI distribution amplifier 

 

The DDA108A-BP may be used with the RM01 single slot rear connector, the RM02 
quadruple slot rear connector and the RM18 double slot rear connector. If relay bypass is 
required the rear module used is the RM38. A single slot rear connector provides five 
equalised outputs and three extra outputs are available with the double and quadruple slot 
connectors. 

It is very compact with 12 modules fitting in a 2U frame when a single slot rear connector 
is used.  

Further rear connector details may be found in the Installation chapter. 

The main features are as follows: 

 

1 in 8 out DVB-ASI/SDI distribution amplifier  

 

Automatic equalisation for up to 250 metres of coaxial cable 

 

LED input presence indication 

 

Card edge control 

 

Relay bypass available with the RM38 rear module
