Crystal Vision Introduction
3GDA105/111 User Manual R1.22 10 February 2021
1Introduction
The 3GDA105/111 is a family of 3G High Definition distribution amplifiers, which can
distribute 3G HD, HD or SDI signals. Depending on the configuration of each version,
these 3G HD distribution amplifiers provide five reclocked or non-reclocked outputs or
by the addition of a sub PCB eleven reclocked or non-reclocked outputs. Auto input cable
equalisation and output drivers ensure an SD cable length of in excess of 250 metres with
Belden 8281 or equivalent and up to 140 meters for HD and 80 metres for 3G HD with
Belden 1694 or equivalent is obtainable.
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 and switch positions as an
indication of input present, HD/SD and PSU status when opened.
3GDA105/111 multi-standard distribution amplifiers
The 3GDA105/111 family consists of four models. The two basic models are the
3GDA105C one in five out reclocking DA and the 3GDA105N one in five out non-
reclocking DA. The addition of a six output sub PCB increases the total number of
outputs available to eleven as specified in the 3GDA111C and 3GDA111N respectively.
The 3GDA105N and 3GDA111N versions were made obsolete in 2018.
For simplicity all four boards have no comms ability and where user configurable, they
are configured via an on-board link or switch.
The 3GDA105C/N use the RM41 single-slot rear connector with six BNC connectors, the
3GDA111C/N use the addition of a RM34 in the slot above to increase the number of
outputs to eleven.
The 3GDA family of boards is very compact with up to 12 modules fitting in a 2U frame
when a single slot rear connector is used.
The rear connector details may be found in the Installation chapter.
The main features are as follows:
•Up to one in eleven out HD/SD reclocking or non-reclocking.
•Automatic input cable length equalisation.

2Hardware installation
The 3GDA105/111 digital video distribution amplifiers fit into all Crystal Vision rack
frames. All modules can be plugged in and removed while the frame is powered without
damage.
2.1 Universal rear connectors
The 3GDA105C and 3GDA105N use a single height rear connector, this will allow the
2U Indigo 2 frame to house 12 modules and dual power supplies. The 1U Indigo 1 will
house six modules with a single power supply. The Indigo DT desk top box has a built-in
power supply and will house up to two modules.
The 2U and 1U frames all have a hinged front panel that gives access to the PSUs and all
modules. The desk top box also has a removable front to gain access to the modules. The
universal frame wiring system allows any of the interface range of modules to be fitted in
any position with the use of removable rear modules.
The 3GDA111C and 3GDA111N use a second single slot rear connector to obtain the full
number of outputs, this means that packing density will be reduced.

2.2 General purpose interface
The external GPI control lines 'a' to 'f' at the frame remote connectors are provided to
allow remote control and/or remote status indication. Line 'a' is assigned as a GPI output
to provide remote indication of input presence.
The GPI output is fitted with 6k8Ω pull-up to +5V and 270Ωseries resistor so it can drive
an LED directly. If the series resistor is shorted out, it can drive a bulb at +45V 500mA
max.

initial aid to trouble shooting.
Fault finding guide
The Power OK LEDs are not illuminated
Check that the frame PSU is functioning – refer to the appropriate frame manual for detailed
information
Check that the card is seated correctly in the frame
There is no video output
Check that a valid video input is present (input present LED illuminated) and that any cabling is intact
The video output is low quality
Check that the maximum length has not been exceeded
Check that the HD/SD switch is set in the correct position for the input video (‘N’ version only)
