3 Overview
The VM-22HD 2 x 1:2 HD/SD-SDI DA is a high-performance 2 x 1:2
distributor for all SDI video signals. In particular, the VM-22HD:
• Transmits up to 200m
• Accepts two inputs and distributes each signal to two pairs of
identical outputs using BNC connectors
• Has a video bandwidth of 1.485GHz that enables it to be used for
standard-definition and high-definition serial digital video signals
(SD/HD-SDI)
• Also passes digital information (embedded audio, Teletext, time
code, and so on) during the video blanking period
• SMPTE 292M, 259M, 344M, and 372M (dual link application)
compliance and data rates of 143, 177, 270, 360, 540, 1483.5, and
1485Mbps
• Provides automatic, multi-rate, equalization and reclocking to
compensate for losses typical to long runs of 75 Ω co-axial cable
of up to 200m
• Has LEDs indicating the SDI resolution
To achieve the best performance:
• Use only good quality connection cables
1 to avoid 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 that
may adversely influence signal quality and position your Kramer
VM-22HD away from moisture, excessive sunlight and dust
