Dual channel distribution in multi-standard environments
The 3GDA204R is a dual channel reclocking distribution amplifier providing high quality distribution of 3Gb/s, HD or SD sources, with two outputs per channel.
It is the perfect product for those who need to double the outputs on a couple of video feeds.
The two channels are independent allowing you to put different standards through each - perfect, for example, if you have HD and SD copies of the programme you want to distribute.
It can be configured instead to be single input to meet a change in requirement, with input 1 then driving the outputs of both channels.
All outputs are DVB-ASI compatible - a useful feature given the wide use of ASI within the broadcast environment - with all outputs non-inverted.
It is suited to providing high performance distribution for any multi-standard environments, for broadcasters who need to distribute 3Gb/s now or in the near future, and for engineers who want to 'future proof' their SD or HD installations.
Excellent performance
The 3GDA204R gives excellent jitter performance on long cable runs.
With auto detection of input, it will recognise whether the standard is HD or SD and switch the output slew rate automatically, in addition to illuminating the appropriate LED.
The 3GDA204R will always choose an appropriate cable equaliser for the signal type, ensuring an SD cable length in excess of 250m with Belden 8281 or equivalent, and up to 140m for HD and 80m for 3Gb/s with Belden 1694A - with no data errors.
Local monitoring is available, with LED indication of inputs and power supplies present.
Monitor your signals
The 3GDA204R is ideal for those seeking information about their signal, especially in big systems.
Your broadcast control system will know whether every DA in the system has got an input. It provides remote monitoring of input present and 3G/HD or SD signal, using either the integrated control panel on the AE frame, a remote control panel, GPIs, SNMP, our ASCII and JSON protocols, the Statesman Lite PC software or the VisionWeb Control web browser software. Try the 3GDA204R VisionWeb demo...
SNMP additionally allows alarms to be set on loss of input and change in signal type.

Save rack space - and protect your output
Fitting in the Crystal Vision Indigo frames (available in 2U, 1U and desk top box sizes), this space-saving single height 100mm x 266mm module sits in one frame slot allowing up to 12 DAs (24 channels) in 2U.
It uses either the RM75 frame rear module or the RM76 rear module to access the two 3Gb/s, HD or SD inputs and two outputs per channel.
The RM76 includes dual relay bypass protection on power failure or board removal, protecting both inputs to give that extra layer of security and prevent signal loss.

Weight: 140g
Power consumption: 3.5 Watts
VIDEO INPUT
Two independent 3Gb/s or HD or SD inputs. Channels can be of different video standards
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to SMPTE 259 or ASI data, SMPTE 292-1 and SMPTE 424/425-A
3Gb/s cable equalisation up to 80m with Belden 1694A or equivalent
HD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281)
SD cable equalisation >250m Belden 8281 or equivalent
Input return loss: -15dB for 50MHz to 1.5GHz
Auto detection of input – recognises whether the standard is 3G/HD or SD and switches the output slew rate automatically
VIDEO OUTPUTS
Two reclocked 3Gb/s, HD or SD outputs per channel using RM75 or RM76 frame rear modules
The RM76 frame rear module provides dual relay bypass protection. An electromechanical relay switch needs power to hold the switch in one state and will revert to the other state (board bypass) on loss of power. It prevents signal loss by mechanically connecting each input of the 3GDA204R to its first output on complete frame power failure or board removal

What outputs do I get?
Signal inputs and outputs are accessed by using an appropriate rear module.
The Indigo rear modules slot on to the back of the frame and typically feature BNC, D-Type, RJ45 and optical connectors. The single and double slot rear modules can be used with all three frame sizes, while the quad slot rear modules just fit the 2U frames.
The 3GDA204R is DVB-ASI compatible: all outputs are non-inverted.
