7751SRG-HD

HD-SDI Tri-Level Sync Generator

The 7751SRG-HD generates various analog bi-level & tri-level sync signals for both HD and SD applications. The 7751SRG-HD provides an analog genlock input that allows you to synchronize the sync signals to your plant horizontal and vertical timing.

The 7751SRG-HD generates all analog sync signals defined by SMPTE 274M (1080i/p) and SMPTE 296M (720p) as well as those required for NTSC, PAL and slow PAL (625i/48) applications. Sync signals generated for NTSC, PAL and slow PAL applications are sync signals only and do not incorporate color burst signals. The four independent sync outputs can be configured to output different sync signals. The common combinations of HDTV and SD analog sync outputs can be selected via card edge control.

In conjunction with the 7700ADA7 Analog Distribution Amplifier and the 7751TG2-HD HDTV Test Signal Generator, this module will fulfill all of your slave sync generation requirements. Should a failure occur, using the 7700ACO-HD or 500ACO2-HD/SD in conjunction with the 7751SRG-HD makes for a high availability of master reference throughout the plant.

Features

  • NTSC or PAL colour black genlock or free-runs with no genlock reference
  • Phase adjustment of outputs with respect to genlock input
  • Selectable frame rate divisor of 1 or 1/1.001
  • Wide variety of 1080i, 1035i, 1080p, 720p and NTSC/PAL/slow PAL sync output sync signals (excluding burst)
  • HSDL tri level sync for 2K data transfers
  • 4 separate analog sync signal outputs
  • 6Hz or 1Hz TTL pulse shows relationship between HD & SD Sync outputs
  • 8 position DIP switch selects combinations of sync signal available
  • Card edge LEDs indicate genlock presence, module fault
  • VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
