I. Introduction
The SDI to VGA scaler converter allows SD-SDI, HD-SDI and 3G-SDI signals to be shown on VGA
displays while ensuring high bit rates of 2.970 Gbit/s to give you fast signal transmission without any
loss. For professionals this means that it is now easier to distribute and extend your 3G SDI signal while
giving you the ability to display your work on VGA displays thanks to the built in this converter.
Furthermore, thanks to the loop-through 3G-SDI design, users are able to enjoy both SDI and VGA at
the same time.
II. Features
1. Operation at 2.970Gbit/s, 2.970/1.001Gbit/s, 1.485Gbit/s, 1.485/1.001Gbit/s and 270Mbits/s
2. Equalized and re-clocked loop output
3. Auto video mode detection (3G/HD/SD)
4. Conversion from SMPTE 425M level B to Level A 1080p 50/59.94/60 4:2:2 10-bit

5. Connect with other units to extend your signal over long distances
6. Simultaneous display with SDI /VGA signals
7. Alternative audio output to analog 2CH
8. Supports signal transmission distances of up to 300M for SD signals, 200M for HD signals and
100M for 3G signals
9. Note: Cable tested with Belden 1694A. Operating distances may vary if used with another type of
cable.
