GeckoFlex 8985FS HD/SD Frame Synchronizer

The 8985FS is a compact, high-performance, fiber-ready HD/SD frame synchronizer board with low hysteresis, a dual-redundant reference capability, and a perfect-picture mode. This board is therefore suited to production and playout applications where high reliability is required.

The 8900GEN-SM sub-board provides a dual-redundant reference to ensure continuous glitch-free operation even when the incoming reference signal fails. Perfect-picture mode prevents damaged frames and picture stutter from appearing when the incoming feed fails.

Fiber-ready technology allows this board to accept one of three types of SFP fiber optic sub-boards. One of these can be installed in the fiber optic rear cage connector to provide two fiber inputs (Dual Receiver), two fiber outputs (Dual Transmitter), or one fiber input/one fiber output (Transceiver).

The 8900NET board is required for web browser or Newton control panel configuration. In addition, NetConfig and CommandCenter can be used for remote configuration and SNMP signal health monitoring.

  • HD/SD frame synchronizer
  • Operates in frame sync and delay modes with user-programmable delay, plus a framing delay from 300 pixels up to eight frames minus 5 lines in pixel-sized steps
  • Supports genlock sub-board to manage reference timing (required for frame sync operation)
  • Genlock sub-board supports Tri-level sync and NTSC/PAL color black and loop-through
  • Split screen mode for in/out comparison
  • Accepts an optional fiber transmitter, fiber receiver, or fiber transceiver SFP device providing optical HD-SDI and SD-SDI I/O
  • With asynchronous sources where SD-SDI and HD-SDI line or frame synchronization is required
  • With synchronous sources to compensate for cable or processing delays
  • When a video signal needs timing adjustment to match other sources
  • With live signals where minimum delay is important

Electrical Length (delay)
Fixed delay mode:
  • Nominal: 1 frame (±1 pixel)
  • User-adjustable range: 1 frame minus 5 lines to 2 frames minus 5 lines
Synchronizing mode (asynchronous input):
  • Minimum: 1 frame minus 5 lines
  • Maximum: 2 frames minus 5 lines
Fixed delay mode = in minimum delay mode:
  • Nominal: 300 pixels (±1 pixel)
  • User-adjustable range: 300 pixels to 1 frame minus 5 lines
Synchronizing mode = in minimum delay mode (synchronous input):
  • Nominal: 300 pixels (±1 pixel)
  • User-adjustable range: 300 pixels to 1 frame minus 5 lines
Additional adjustable delay: 0 to 6 additional frames

Genlock (reference signal):
The 8900GEN-SM sub-board is required for genlocking GeckoFlex boards with frame sync.

The 8900GEN-SM sub-board attaches to the front board and provides genlock reference support to:
  • Host synchronizer board
  • Host synchronizer board and one of two chassis reference buses
  • Other GeckoFlex boards via the chassis reference bus
A second sub-board attached to another GeckoFlex board can provide redundant chassis reference or a different signal format. (NOTE: at least one board per chassis must have a genlock sub-board installed to provide reference bus support).

Reference signal to timing pulse edge: Adjustable from 0 to 1 frame in 1 SD pixel steps
