3 Overview
The VM−2HDxl is a high−performance distribution amplifier for 3G HD−SDI
signals. The unit takes one input, provides reclocking and equalization and
distributes the signal to two identical outputs.
In particular, the VM-2HDxl features:
 Cable equalization up to 300m
300m for SD signals; 200m for 1.5GHz HD signals; 100m for 3GHz HD signals
(measured with Kramer BC-1X 1 Coax RG-6 Super High-Resolution Cable).
 One input and two identical outputs on BNC connectors
 A data rate of up to 3Gbps, that enables it to be used for standard definition, high
definition and the 3G high definition serial digital video signals (SDI, HD-SDI and
3G HD-SDI)
 HDTV compatibility
 Passing of digital information (embedded audio, Teletext, time code and so
on) during the blanking period
 SMPTE 292M, 259M, 344M and 424M compliant with data rates of
270Mbps, 540Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps
 Automatic, multi-rate, equalization and reclocking for losses typical with long
runs of 75 co-axial cable up to 300m
 LEDs indicating the SDI resolution (SD or HD)
