General
Dimensions
266mm x 100mm module with DIN 41612 connector
Weight
230g
Power consumption
8 Watts (ShARC102-XP), 8.4 Watts (ShARC204-XP)
Inputs
Video SDI inputs
One input with ShARC102-XP
Two inputs with ShARC204-XP
SDI 270Mbit to EBU 3267-E & SMPTE 259M
Cable equalisation
>200m Belden 8281 or equivalent
Line selection
Auto 625/525 line selection
Blanking
All data in the vertical and horizontal blanking interval is passed
through unprocessed with full 10 bits. Therefore, the unit will pass
through embedded audio and any ancillary data with a 10
s
propagation delay.
Outputs
Video SDI outputs
One output with ShARC102-XP
Two outputs with ShARC204-XP
ShARC102-XP
2 x 270Mb/s serial digital to EBU Tech 3267-E and SMPTE-259M
ShARC204-XP
4 x 270Mb/s serial digital to EBU Tech 3267-E and SMPTE-259M
Horizontal picture
conversions
16:9 to 4:3 conversion stretches middle 75% of picture to fill
whole screen
4:3 to 16:9 conversion squashes picture to fill 75% of screen
creating a pillarbox with black vertical bars.
No vertical conversion
Frequency response
16:9 to 4:3 is virtually distortion free
4:3 to 16:9 output frequency response 0 to 5.5MHz
This corresponds to input frequencies of 0 to 4.1MHz
The squashing of the picture raises the frequency spectrum of the
picture and so the anti-aliasing filters can cause a loss of very fine
detail
Delay through board

s
Picture processing
10 bit with 10 bit data path in horizontal and vertical blanking
interval to allow embedded audio or data
