MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 200g
Power consumption: 11 Watts (plus 0.6 Watts for FIP or FOP)

INTEGRATED FIBRE OPTIONS
AVDELAY 3G can be given integrated fibre connectivity by fitting either the FIP fibre input option or FOP fibre output option. The chosen option should be fitted at the factory
To access the optical inputs or outputs an RM62 frame rear module must be used
When fitted with a FIP or FOP, AVDELAY 3G can be housed in any frame slot position but due to its extra height it is not possible to place Standard Definition or audio boards directly above it when the AVDELAY 3G is in even numbered slot positions. 3Gb/s and HD boards do not share this restriction
FIP and FOP meet the SMPTE 297-2006 short-haul specification, allowing operation with single-mode and multi-mode fibre
Connector type: SC/PC
FIP:
Optical wavelength: 1260-1620nm
Input level maximum: -1dBm
Input level minimum: Typical -20dBm (-18dBm 3Gb/s pathological)
FOP:
Optical power: Max -0.0dBm, min -5.0dBm (typical -2.0dBm or 630uW)
Fibre pigtail: Single-mode 8/125uM
Optical wavelength: 1290-1330nm (1310 typical)
Extinction ratio: 7.5dB
Laser safety classification: Class 1 (EN 60825), Class I (21CFR1040.10)

VIDEO INPUT
One 3Gb/s, HD or SD input
When using FIP fibre input option allows selection between one optical and one BNC input
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to EBU 3267-E, SMPTE 259M, SMPTE 292M and SMPTE 424M
3Gb/s cable equalisation up to 80m using Belden 1694A. HD/SD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281)
Input return loss: -15dB for 50MHz to 1.5GHz and -10dB for 1.5GHz to 3GHz

VIDEO OUTPUTS
Using RM62 rear module with no fibre option or FIP fibre input option: Two delayed 3Gb/s, HD or SD outputs
Using RM62 rear module with FOP fibre output option: Two delayed 3Gb/s, HD or SD outputs along with a copy of the output on fibre
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to EBU 3267-E, SMPTE 259M, SMPTE 292M and SMPTE 424M

EMBEDDED AUDIO
Can contain up to four groups of embedded audio

MAXIMUM VIDEO/AUDIO DELAYS
The maximum video delay will change depending on the video standard. The maximum audio delay remains the same, irrespective of standard

MINIMUM VIDEO/AUDIO DELAYS
Minimum video and audio processing delay of one frame

AUDIO/VIDEO DELAY ADJUSTMENTS
Audio and video delay are independently adjustable, allowing the user to change the relative audio/video timing in either direction
Video delay is adjustable in seconds and frames
The audio delays are adjustable in seconds, video frames and milliseconds
Three default buttons allow the operator to set all the video and audio delays to 0, 5 or 10 seconds
The audio and video will jump instantly to the new delay setting

AUDIO DELAY BLOCKS
There are four separate audio delay processors and each mono audio channel can be assigned to any one of them, or to bypass the delay completely

DOLBY E
Dolby E can be assigned to the four audio delay settings in the same way as other audio. Both channels of a Dolby E signal will be assigned to the same delay
AVDELAY 3G automatically aligns the guardband with the outgoing video. The delay applied to the Dolby E will be the delay setting rounded to the nearest time that gives the correct guardband alignment

LED INDICATION OF:
Power supplies on board
HD/SD input
Input audio groups present
GPI output 6 active

GPI INPUT LEVELS
Active pull to ground, pulled up to +5V through 7 kohm

GPI OUTPUT LEVELS
Electrically: Open collector transistors 30V, 270 ohm current limit resistors. Pulled up to +5V through 7 kohm

GPI INPUTS
Four GPI inputs can recall one of 16 presets

GPI OUTPUTS
One GPI output (GPI 6) is reserved for alarm indication. It may be assigned any number of 21 video and audio alarms:
Video Missing
Input group 1 missing
Input group 2 missing
Input group 3 missing
Input group 4 missing
Silence group 1 channels 1 and 2
Silence group 1 channels 3 and 4
Silence group 2 channels 1 and 2
Silence group 2 channels 3 and 4
Silence group 3 channels 1 and 2
Silence group 3 channels 3 and 4
Silence group 4 channels 1 and 2
Silence group 4 channels 3 and 4
Dolby E on input group 1 channels 1 and 2
Dolby E on input group 1 channels 3 and 4
Dolby E on input group 2 channels 1 and 2

Dolby E on input group 3 channels 3 and 4
Dolby E on input group 4 channels 1 and 2
Dolby E on input group 4 channels 3 and 4
Video missing and input groups missing will assert an alarm immediately. The silence alarms can be delayed by up to 128 seconds before an alarm is asserted to prevent false alarming during quiet audio periods
