MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 200g
Power consumption: 7.4 Watts
VIDEO SDI INPUT
SDI 270Mbit to EBU 3267-E & SMPTE 259M
Cable equalisation >200m Belden 8281 or equivalent
Auto 625/525 line selection
ANALOGUE REFERENCE
Composite Black and Burst
Amplitude of syncs 300mV +/- 10%
Link on PCB selects 75ohm termination or high impedance
with loop-through (via PCB)
OUTPUTS
Reclocked SDI loop-through. Will drive >200m Belden
8281 or equivalent
Composite reference loop-through (depending on frame
type, rear module and board link position)
Three analogue outputs with RM01 frame rear module,
five with RM02 and six with RM18
On-board links allow the selection of all composite
outputs, or a mixture of composite and Y/C outputs
ANALOGUE PERFORMANCE (COMPOSITE OUTPUT)
Frequency response: 0.1dB 0 to 5.5 MHz
Differential Phase: <1 degree
Differential Gain: <1%
Noise: <-60dB weighted
Blanking: To PAL/NTSC specification horizontally and
vertically with selectable VBI blanking. PAL lines to
22 and 320 to 335 and NTSC lines 10 to 20 and 273 to
282. Active PAL lines 6 to 22 and 319 to 335 is available
as a menu selectable option
Delay: Reference input to composite output is -4us to
4.9 lines. For zero delay, serial video input must be
at least 4.3us before output
Output timing can be set to be the same as the analogue
reference, or it can be offset by the user to be between
4us earlier than the reference and 4.9 lines later.
The SDI video input must be earlier than the required
output by a minimum of 4.3us and a maximum of 4.9 lines.
If the input is outside of this window a valid composite
output will still be created, but the content of the
picture will be vertically offset
LED INDICATION OF:
Power supplies on board
SDI input present
SDI input lock error
625/525 input standard
Genlock reference present
Reference lock error, or mis-terminated reference
Output not phase-locked to input
Input out of TBC range. Indication is given of early
by <5 lines, late by <5 lines and more than 5
lines out of range
LOCAL CONTROL
Variables and options set by shaft encoder with values
and prompts on 10 character alphanumeric display on
board edge. These variables may also be set remotely
Output timing relative to reference can be set by vertical
offset, horizontal course adjustment, horizontal fine
adjustment and horizontal sub-pixel adjustment in 2.3ns
steps. SCH phase can be adjusted in both coarse and
fine steps of 1/2 degree and 1/16 degree respectively.
There are adjustments for YUV gain, burst gain, luminance
gain, chroma gain and individual U and V gain
The amount of setup (when selected) can be set
REMOTE CONTROL
RS422/485 and RS232
19200 baud 8 bits, 1 stop no parity
2 serial ports - 1 connected to frame front panel, 1
can be linked to rear of frame instead of GPI signals
Front panel control from frame active panel and remote
panel
Statesman allows control from any PC on a network
