About This Manual

This manual describes the features of a specific module of the 8900 Series
Modular Products family. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the 8900 Series frame and
power supply documentation (see the

8981FS Digital Frame Synchronizer Module

Introduction

The 8981FS is a component digital frame synchronizer module compatible
with the 8900 series frames. The video input and output are 270 Mb serial
digital and reference is analog color black. The module can also be operated
as a fixed delay with adjustable output timing offset relative to the video
input. This mode does not require a reference input.

The 8981FS combines the best features of a frame synchronizer, frame delay
and digital processing amplifier in one module. It is designed to handle
various environments and applications including asynchronous input
video signal timing, manual color correction, and production freeze frame
applications. It operates as a companion to the 8916 AES/EBU Auto­tracking Delay DA for audio synchronization applications. The 8981FS
offers several control modes including:

■

Local onboard controls,

■

GPI (general purpose interface) for freeze mode trigger, and

■

Ethernet control over a LAN/WAN using the optional 8900NET control
system.

8981FS Instruction Manual 1

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 ref­erence 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 GUI­based configuration and monitoring system (see

and Monitoring on page 17

■

Can provide various freeze options for production applications that are

).

Remote Configuration

triggered by either a GPI (general-purpose interface) using a BNC con­nector or by remote control via the 8900NET control system.

Installation

Frame Capacity

Installation

Installation of the 8981FS module consists of:

1.

Placing the module in the proper frame slot, and

2.

Cabling and terminating signal ports.

The 8981FS module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica­tors reflect the initialization process (see

Power Up on page 7 ).

The 8981FS module can be installed in all 8900 Series frames but with
varying maximum quantities determined by frame cooling capacity.

Table 1 provides the power capacity, cooling capacity, and maximum

module count for each frame type.

Module Placement in the 8900 Frame

There are ten slot locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to Figure 1.

The two slots on the right are allocated for the power supplies. For addi­tional information concerning the Power Supply module, refer to the 8900
frame manual.

The third slot from the right is allocated for the controller module—either
a Frame Monitor Module or a Network Interface Module. For additional
information concerning the controller module options, refer to the

8900 modules are interchangeable within the module slots. There are 10
BNC connectors in each slot’s I/O group. The functional assignment of
each connector in a group is determined by the module that is placed in
that slot. The maximum number of modules an 8900 frame can accept is
ten. Figure 2 illustrates the rear connector plate for an 8900 Series frame.
