Overview

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 75Ω co-axial cable

of up to 200m

• Has LEDs indicating the SDI resolution

To achieve the best performance:

• Use only good quality connection cables

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
