8985FS SD/HD Video Frame Synchronizer
The 8985FS is a compact, high-performance,
fiber-ready SD/HD frame synchronizer module
with low hysteresis, a dual-redundant reference
capability, and a perfect-picture mode. This
module is therefore suited to production and
playout applications where high reliability is
required.
The 8900GEN-SM submodule 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 module to
accept one of three types of SFP fiber optic
submodules. 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 (Net Card) module is required
for Web browser or Newton control panel
configuration. In addition, NetConfig
and NetCentral can be used for remote
configuration and SNMP signal health
monitoring.
Refer to the rear module pinout and block
diagram on the next page.
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
Synchronizing
Genlock (reference signal):
The 8900GEN-SM submodule is required for
genlocking GeckoFlex modules with frame sync.
The 8900GEN-SM submodule attaches to the front
module and provides genlock reference support to:
• Host synchronizer module
• Host synchronizer module and one of two frame
reference buses
• Other GeckoFlex modules via the frame reference
bus
A second submodule attached to another GeckoFlex
module can provide redundant frame reference or a
different signal format. (NOTE: at least one module
per frame must have a genlock submodule installed to
provide reference bus support).
Reference signal to timing pulse edge: Adjustable
from 0 to 1 frame in 1 SD pixel steps.
Control And Monitoring
SNMP: Yes
Web page configuration: Yes
Local configuration: No
Newton support: Yes
NetConfig support: Yes
NetCentral support: Yes
Applications
•
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
Ordering Information
This module can be mounted in a GeckoFlex
frame but not in other 8900 series frames,
including Gecko-A or Gecko-V frames. As this
module has no card-edge controls, an 8900NET
(Net Card) Network Interface module is required
to configure the module.
