LYNX YELLOBRIK SYNC PULSE GENERATOR – SD, HD, 3G SDI – Genlock
Part of the Yellobrik range of modules manufactured by Lynx Technik, the SPG 1708 is a versatile analogue sync-pulse generator with genlock, that will deliver simultaneous sources of HDTV and SDTV sync and audio reference signals including 3G-SDI 1080p and 12G-SDI 4K-UHD.
The genlock capability is the strong point of the SPG 1708; it will cross-lock to any sync signal regardless of the output sync format selected, useful if a source of HDTV tri-level sync is needed, locked to a SDTV black reference, or if it is needed to lock across standards, for example, to connect to a PAL sync and get frequency-locked NTSC sync and HDTV tri-level sync outputs.
The module provides three SD sync outputs and three HD sync outputs and a separate audio sync output that can be switched between 48kHz word clock or Digital Audio Reference (DARS). Flexible genlock capability allows the module to genlock to any SD or HD reference input, with full cross-lock capability, even across unmatched standards. The HD tri-level sync outputs can be set to any of the available HD standards, and the bi-level SD outputs set for NTSC, PAL or PAL M/N. The SD and HD sync outputs and audio sync signals are all frequency-locked to the reference regardless of the selected sync standard for the outputs. The SD sync outputs can be colour bars, black burst or sync only with selectable 7.5 IRE pedestal for NTSC standards, with adjustable burst phase in 8 increments.
The module has eight BNC connectors, three each for SDTV and HDTV sync outputs, one for the audio reference, one for the sync reference input. The generator is robust and temperature stabilised, suitable as a reference source with 2ppm accuracy. All user controls are located on the top of the module, clearly labelled and easily accessible. A rotary switch selects sync output; an LED indicates genlock. A USB port is provided for firmware upgrades. SPG 1708 is also compatible with RCT 1012 yellobrik control IP interface module.
