Datasheet
SDM-1151
5-Channel SDI to Composite Monitoring
Space-saving, modular platform for advanced signal processing.
The SDM-1151 from Grass Valley, a Belden Brand, provides five channels of SDI to composite analog video
conversion.
The SDM-1151 is a high-density, cost-effective solution for many monitoring applications. Within a single
Densité frame, up to 50 channels can be converted. Each channel includes a high quality 8-bit converter that
can auto-detect 525 or 625 line formats.
The composite outputs can be pre-equalized for up to 100m (328 ft.) to avoid chroma loss. A luminance-only
mode is available for monochome monitoring applications. Built-in test generators can provide a color bar
signal to each composite output.
The SDM-1151 also provides input validity and error detection reporting.
