SPG 1707

HD / SD Sync Pulse Generator with Genlock

Datasheet Quickreference Application Notes


The SPG 1707 is a compact, versatile analog sync pulse generator with genlock providing HD / SD video sync and audio reference signals. The module provides three SD sync outputs and three HD sync outputs and a separate audio sync output that can be switched between 48 KHz 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 Color bars, Black Burst or Sync only with selectable 7.5 IRE pedestal for NTSC standards with adjustable burst phase in 8 increments.  
The sync generator is robust and temperature stabilized, suitable as a reference source with 2ppm accuracy.  
All user controls are located on the top of the module clearly labelled and easily accessible. This facilitates simple changes to module function and configuration without referring to a manual.  
The compact portable design makes it suitable for a wide range of applications in broadcast and mobile production environments.  
Note: 1080p 50Hz / 60Hz and 59.94Hz sync standards not supported.
