3 Overview
The
VM-20HDxl
3G Dual 1:10 HD/SD - SDI Distribution Amplifier
is a high
performance dual channel distribution amplifier for SDI (SMPTE 259M and
SMPTE 344M) and HD-SDI (SMPTE 292M) signals. It will take one input
per channel, provide reclocking and equalization and distribute each signal to
10 dual outputs, using BNC connectors.
In particular, the
VM-20HDxl
:
Can be configured as a 1:20 DA
Has an active loop BNC connector on each channel, for cascading
additional units
Has a data rate of up to 2.97Gbps – enabling it to be used for standard
definition, high definition and the new 3G high definition serial digital
video signals (SD/HD-SDI)
Supports up to 300m cable equalization (300m for SD signals, 200m for
1.5Gbps HD signals, and 100m for 3Gbps HD signals)
Is SMPTE 259M, 292M and 424M compliant and supports data rates of
270Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps
Provides automatic, multi-rate, equalization and reclocking for losses
typical with long runs of 75 co-axial cable
Has HD and SD output indication LEDs for each channel
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching,
and elevated noise- levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position
your Kramer
