VSG-4MTG
Master Timing Generator
The VSG-4MTG is part of the Harris’s new Sync and Timing platform, the ½RU-wide, 1RU tall and 12 inches deep, 3G/HD/SD master timing generator. The unit is small in size, redundant power supply inputs, low power consumption and light in weight, making it a perfect fit for all broadcast television and post production environments.
The VSG-4MTG provide multiple timing inputs that include GPS with 10 MHz and PPS inputs, LTC, NTP, VITC support and future support for IEEE1588 PTP via software upgrade available in the fall of 2012. The video reference input supports NTSC, PAL, SD, HD and 3G formats of video source sync signals including Black Burst (BB) or Tri Level Sync (TLS). The rock solid internal oscillator provides the needed stability for all timing applications.
The VSG-4MTG provide outputs that include NTP master, PTP master, VITC, BB, TLS and LTC outputs with individual offsets on all outputs. Both models also provide for DARS or Word Clock (WC) output. The new easy to use front panel allows for instantaneous status on any source or output including date, time and lock information. This Master Timing Generator provides for daylight savings time and time zone offsets, auto change over for source failures with primary and secondary source selection. The fail over provides the next best choice of maintaining the uninterruptable status that is required by the most stringent systems.
The VSG-4MTG provides 5 sync outputs as BB or TLS with individual offsets and formats. This provides for multiple format timing from a single reference source.
The unit has dual power supply capabilities using external 110/220 universal AC adapters providing the required DC power input.
