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. www.grassvalley.com 1 SDM-1151 5-Channel SDI to Composite Monitoring KEY FEATURES • • • • • • • • • 5 SDI digital video inputs 5 composite analog video outputs Adjustable Pre-EQ (up to 100m/328 ft.) on each composite output Exceptional density of 25 channels per RU 8-bit D-to-A conversion Internal test generators (color bars) Supports both 525 and 625 line formats VBI passed (Vbit handling) Luminance-only mode available 1 SDI to Composite Converter Pre-EQ 1 Pre-EQ 2 Pre-EQ 3 Pre-EQ 4 Test Gen. 2 SDI to Composite Converter Test Gen.
