3GDA111C
What is it?
3G/HD/SD reclocking distribution amplifier.
Reason to choose it...
You can do a lot with eleven outputs. It's equally suited to distributing 3Gb/s, HD or SD signals – meaning no need to rush out to replace it when you upgrade. You'll get excellent jitter performance as well as saving yourself rack space (with six DAs fitting in 2U). It's the distribution amplifier to choose when you do need signal reclocking but don't need signal reporting.
Ideal for...
High performance distribution in multi-standard systems when you need multiple outputs. See who's using it.

Distribute signals in multi-standard environments
The 3GDA111C is a reclocking distribution amplifier providing high quality distribution of 3Gb/s HD, HD or SD sources.
It gives eleven reclocked outputs.
All outputs are DVB-ASI compatible - a useful feature given the wide use of ASI within the broadcast environment - with a mixture of non-inverted and inverted outputs.
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 3GDA111C 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 3GDA111C 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 input and power supplies present.
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 'double decker' 100mm x 266mm module sits in two frame slots allowing up to six DAs in 2U.
It uses either the RM41 and RM34 frame rear modules together or the RM67 and RM34 rear modules together to access the one 3Gb/s, HD or SD input and eleven outputs.
The RM67 includes relay bypass protection, guaranteeing the maintenance of one output in the event of power failure or board removal.

VIDEO OUTPUTS
Eleven reclocked 3Gb/s, HD or SD outputs using RM41 and RM34 frame rear modules together or RM67 and RM34 rear modules together
The RM67 frame rear module provides 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 the input of the 3GDA111C to one of its outputs on complete frame power failure or board removal
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. Output follows the input format
All outputs are DVB-ASI compatible, with nine non-inverted outputs and two inverted outputs
DELAY THROUGH BOARD

GPI OUTPUT LEVELS
Electrically: Open collector transistors 30V, 270 ohm current limit resistors. Pulled up to +5V through 6800 ohm

LOCAL CONTROL
DIP switch on the board edge can be set to either auto detect input (up position) or to force output drivers' slew rate (down position)
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 3GDA111C is DVB-ASI compatible: outputs B, C, D, F, G, H, I, J and K are non-inverted and outputs A and E are inverted.
There are two rear module combinations available for the 3GDA111C...
