Ensemble Designs 7410 Quad HD Tri-Level Sync Generator - Manual (Page 2)

MODULE OVERVIEW
The 7410 module is a stable timing source suitable for local reference generation for use
in broadcast, remote trucks and post-production. Four simultaneous HD tri-level sync
reference outputs are provided. Each output can each be set to a different HD standard.
The 7410 can operate from an internal precision frequency reference as a stand alone
master sync generator or lock to a PAL or NTSC video reference from an external source.
There are two video reference inputs on the 7410 module for maximum system flexibility.
The module can also lock to an external 10 MHz source such as an atomic standard or
GPS receiver for more precision.
Each of the four outputs can be timed with respect to the selected reference to any point
in the television frame. Timing adjustments are configured independently and the 7410
can be configured to output 525 and 625 standards simultaneously.
As shown in the block diagram below, the time base reference is selected from either the
Master reference or of of two Genlock (external) references. The selected reference passes
through a precision sync separator to derive the required sync components. The separated
sync signal provides the timing reference for the PLLs.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.
The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), and power status to the optional frame System Control
module. This information can be accessed by the user or set to register an alarm if desired
using the remote control options available.
