GS12070 UHD-SDI Gearbox Key Features Description Fully standards compliant turnkey solution enabling a The GS12070 is a highly configurable UHD-SDI Gearbox simplified UHD-SDI interface which performs multiplexing and de-multiplexing Converts between HD-SDI, 3G-SDI, 6G UHD-SDI, and necessary to facilitate conversions between SMPTE ST 12G UHD-SDI using MUX (Multiplex) and DeMUX 425-3 and/or ST 425-5 (multi-link 3G-SDI) Interface and (Demultiplex) modes SMPTE ST 2081-1 (6G UHD-SDI) and/or ST 2082-1 (12G Quad Link 3G-SDI Single Link 12G UHD-SDI Quad Link (1.5Gb/s x 4) HD-SDI Single Link 6Gb/s UHD-SDI) Interfaces. The Gearbox also supports conversion Quad Link 6G UHD-SDI Dual Link 12G UHD-SDI between 4 x HD-SDI and 6Gb/s SDI. Quad Link 3G-SDI (ST 425-5/6) Dual Link 6G UHD-SDI ST 425-5 ST 2081-11 ST 2082-10 Dual Link 6G UHD-SDI Single Link 12G UHD-SDI Quad-link 3G Dual-link 6G Single-link 12G Dual Link 3G-SDI (ST 425-3) Single Link 6G 3840 x 2160 UHD-SDI p60 Dual Link (1.5Gb/s x 2) HD-SDI Single Link 3Gb/s 4:2:2 10-bit Bypass modes for all supported rates, including SD 4 x 3G 2 x 6G 2 x 6G 12G Automatic skew compensation for multi-link inputs 4 x 3G 12G Automatic input link order handling for multi-link 3Gb/s input Configurable Serial Output assignment Example of Multiplexing ST 425-5 into ST 2081-1 (6Gb/s) and ST 2082-1 (12Gb/s) Configurable multi-link output delay 100 Differential Inputs Input trace equalization up to 12dB For the supported SMPTE conversions, the SMPTE ST 352 Four 100 Differential Outputs payload identification will be automatically detected and Individually selectable output swing replaced based on the user selected conversion mode. This Reference Clock/Crystal Input 27MHz can be bypassed for proprietary multiplexing and GSPI Serial Control and Monitoring Interface Automatic and manual SMPTE ST 352M handling demultiplexing links. 12mm x 12mm 196-Ball BGA (0.8mm pitch) The device incorporates the ability to reorder the output Pb-free/Halogen-free/RoHS/WEEE compliant package serial stream and duplicate outputs to unused output channels or route any input channel. Applications The GS12070 has the ability to automatically compensate Next Generation 3D/2D HFR HDTV and 2K D-Cinema, UHDTV1 and 4K D-Cinema end-equipment: Cameras, for up to 400ns of skew between QL 6Gb/s or DL 12Gb/s Monitors, Switchers, etc. inputs and 800ns of skew between DL 6Gb/s and QL 3Gb/s Next Generation 3G-SDI, 6G UHD-SDI, and 12G inputs. This aids in any lane-to-lane variance introduced by UHD-SDI infrastructures designed in support of cable mismatch or upstream routing and distribution UHDTV1, UHDTV2, 4K D-Cinema and 3D HFR, HDR production image formats, and 6G UHD-SDI/12G equipment. UHD-SDI multiplexing and de-multiplexing for integration into legacy infrastructure.
