MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 200g
Power consumption: 6.5 Watts
VIDEO SDI INPUT
SDI 270Mbit to EBU 3267-E and SMPTE 259M
Cable equalisation >200m Belden 8281 or equivalent
Auto or manual 625/525 line selection
Automatic de-embedding of SMPTE or Sony format
Video input is 8 bit processed for 10 bit output DACs
ANALOGUE VIDEO OUTPUTS
Maximum of five video outputs (depending on rear module)
which can be combination of analogue (RGB, YUV, Y/C,
composite) and SDI
RM04 allows six different output combinations, RM05
and RM06 allow 12 combinations, and RM22 allows 12 combinations
COMPONENT VIDEO PERFORMANCE
YUV and RGB into 75ohm. Y and G 1 volt with syncs. U/V
and R/B 700mV +/-2%
RGB sync: 300mV sync with no burst
Frequency Response:
Luminance: +/-0.2dB to 5.5MHz
Chrominance: +/-0.2dB to 2.5MHz
Noise: <-60dB weighted luminance or chrominance
Gain Error: <1%
COMPOSITE VIDEO PERFORMANCE
Frequency Response:
Luminance: +/-0.2dB to 5MHz
Chrominance: +/-0.2dB to 2.5MHz
Noise: <-54dB weighted luminance or chrominance
Differential Gain: 2% typ.
Differential Phase: +/-0.5% typ.
Blanking: VBI blanking on or off. PAL lines 6 to 22
and 318 to 335. NTSC lines 10 to 20 and 272 to 283.
Conforms to standard digital decompression dimensions
and does not process digital input data for the active
analogue video half lines
AUDIO OUTPUTS
2 analogue stereo pairs or 4 mono channels. Low output
impedance (66ohm) balanced
2 x 20 bit AES/EBU stereo pairs 110ohm balanced or 75ohm
unbalanced
OUTPUT LEVEL RANGE
0dBFS = +28dBu max / 0dBFS = +12dBu min
Factory set default: 0dBFS = +18dBu or +24dBu by on
board jumper link setting
SIGNAL TO NOISE
-82dBu / -100dBFS (+18dBu) rms., 22Hz to 22kHz typ.
TOTAL HARMONIC DISTORTION
0.005% THD+N rms., 22Hz to 22kHz typ.
INTERCHANNEL CROSSTALK
-112dB at 1kHz, -98dB at 20kHz, rms., typ.
MONITORING
1 x miniature front mounting audio jack. Switch selected
for individual stereo audio monitoring
1 x stereo or 2 x mono analogue or 2 x stereo AES outputs
from rear of frame
STATUS MONITORING
Front of card edge visual monitoring with alphanumeric
and LED indicators to indicate:
* PSU rails present: LED
* SDI input: Alphanumeric display
* AES audio input: Alphanumeric display
* Audio silence: Alphanumeric display
GPI INPUTS
4 x GPI allowing the recall of 15 presets
GPI OUTPUTS
2 x GPI for loss of video and audio silence
AUDIO PROTECTION IN DE-EMBEDDER
A variety of sophisticated techniques are employed to
protect and minimise the effects of cuts to untimed
and asynchronous SDI, SDI corruption and TRS loss in
the SDI signal
TEST PATTERNS
PAL 100% EBU Colour Bars
NTSC 75% EIA Color Bars
Fail of input: Blue, Black or Colour Bars selectable
TOOLBOX ANALYSER FUNCTIONS
The Toolbox Analyser provides a detailed analysis of
the SDI input
Reports include: SDI present, audio groups present,
selected audio present, selected audio silent, non audio
HANC data present, audio marked for deletion, audio
data rate OK/high/low, checksum and format errors, parity
error, TRS OK, Video standard = 625/525 lines, Video
Picture Luma Content present/low or missing, Video Picture
Chroma Content present/low or missing
