8981FS Digital Frame Synchronizer Module
8981FS module features include:
■
Provides user-selectable frame synchronization or fixed signal delay.
■
Supports 270 Mb Component serial digital input and output.
■
10-bit signal processing assuring broadcast quality.
■
Adjustable gain and offset of color and luma components.
■
Module is hot swappable (can be removed and replaced while frame
power is on).
■
User settings are stored in non-volatile memory and are maintained
when power is cycled.
■
Output timing/delay and gain/offset settings stored independently for
525 and 625 line operation.
■
Provides automatic 525/625 line selection.
■
Provides delay control signal to drive Grass Valley auto-tracking audio
delay DAs.
■
When operating as a frame synchronizer, output timing is locked to ref-
erence input and adjustable in 37 ns steps over a full frame.
■
Cleanly handles input signal hot switches by momentary freezes when
operating as a frame synchronizer.
■
When operating in Fixed Delay mode, can provide up to one full frame
of output delay adjustable in 37 ns steps.
■
Passes Horizontal and Vertical Interval ancillary data.
■
Monitors its input signal for EDH (error detection and handling) errors
and inserts new EDH on its output signal.
■
Provides user selectable blanking of vertical interval active line data (20
or 21 line in 525; or 24 lines field 1, 25 lines field 2 in 625).
■
Operates in 8900TN Series frames with network control to offer a GUI-
based configuration and monitoring system (see
).
■
Can provide various freeze options for production applications that are
triggered by either a GPI (general-purpose interface) using a BNC con-
nector or by remote control via the 8900NET control system.
