MODULE OVERVIEW
The 5450 Digital Video Frame Synchronizer accepts a serial digital signal for frame syn-
chronization and timing with full 10-bit processing. Four serial outputs, one active loop-
through and two composite monitors outputs are provided, in addition to a reference
input.
The serial input can be non-synchronous, making the 5450 ideal for incoming satellite
feeds, studio signals and for timing sources into a router or switcher. The serial output
timing signal can be set anywhere within one frame of the selected input reference, which
can be the module’s external BNC reference or the frame’s master timing reference.
A composite monitor output is provided through two identical BNCs on the rear of the
5450 module to allow for signal monitoring.
Upon loss of signal or detection of TRS or EDH errors, the 5450 can be set for an interpo-
lated field freeze or blanking to black until the signal is recovered. Internal black and
color bar generators are present on the module. In freeze mode, audio can be muted or
passed as desired. Additionally, a field or frame freeze can be triggered manually or with
GPIs.
As illustrated in the block diagram on the following page, the serial input to the module
enters a receiver circuit where cable equalization is processed and reported. The signal
then moves through a reclocking and EDH detection circuit where the serial steam is
deserialized, descrambled and EDH monitor detection is performed.
The serial output is sent through cable drivers to the reclocked Serial Out BNC. The
10-bit data stream passes through frame synchronizer memory circuitry where it can be
delayed to one frame. Memory control in this section detects TRS and/or EDH errors and
uses them to determine if an automatic freeze should be performed.
The output from the Frame Synchronizer circuitry is then passed to timing and interpola-
tion circuitry which generates output timing and detects presence of audio ancillary data.
This section also generates the internal black and color bars signals which can be inserted
in the data stream upon loss of signal if desired.
This data stream is then sent to a serial encoder and serializer and EDH is inserted and
updated before going to the four serial output BNCs. The same output is also sent to the
composite encoder where the data stream is converted to composite for viewing on the
monitor outputs.
Power is derived from the ± 12 volt frame power. It is regulated to +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.
Module configuration can be set remotely or locally. The status can be read from the
remote interfaces (Avenue PC or a Touch Screen) or from the LEDs on the front of the
module as explained later in this data pack.

APPLICATIONS
The 5450 Digital Video Frame Synchronizer is ideal for applications where serial (601)
inputs to a device such as a router or switcher require retiming. Serial signal sources such
as satellite feeds, studio signals and timing sources that are not synchronous or are out of
time with the facility can be brought into time and made useful for destinations that have
limited input timing capability or auto-timing windows.
The application below shows the output of a DVE device being retimed in the 5450 to
meet the auto-timing window requirements of a digital production switcher.
The 5450 can also be set to freeze the serial data stream or insert black into it when TRS
or EDH errors occur. This can help overcome frame drops and repeats from unstable
sources. A freeze can be also performed manually or from a GPI contact closure.
The delay value being used on the module can be accessed from the remote interface and
utilized in conjunction with audio delay tracking on another module.

INSTALLATION
Plug the 5450 module into any one of the slots in the 1 RU or 3 RU frame and install the
plastic overlay provided onto the corresponding group of rear BNC connectors associated
with the module location. Note that the plastic overlay has an optional adhesive backing
for securing it to the frame. Use of the adhesive backing is only necessary if you would
like the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the module below for cabling
instructions. Note that unless stated otherwise, the 1 RU cabling explanations are
identical to those given in the 3 RU diagram.

MODULE CONFIGURATION AND CONTROL
The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the control mode you will be
using.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 5450 Parameter Table on the following page summarizes and compares
the various configuration parameters that can be set remotely or locally and the
default/factory settings.
If you are not using an remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 5450 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module be moved to a different cell in the frame at your discretion
without losing the stored information. Remote configuration will override whatever the
switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.

TROUBLESHOOTING
As a troubleshooting aid, the input and reference signal, EDH, audio, freeze, EDH error,
power and CPU status can be easily monitored from the front panel of this module using
the LED indicators explained earlier.
If using the Remote mode, the following status items can be monitored using the Avenue
Touch Screen Control Panel or PC Application:
• Input, EDH, Reference and Audio present status
• EDH error status
• Loss of signal (LOS) status
• Slot ID, Software Version and Board Revision
Refer to the overall troubleshooting tips given below for the 5450 module:
No status lights are lit on front panel:
• Check that frame power is present (green LED{s} on frame power supplies).
• Check that module is firmly seated in frame. Try removing it and plugging
it in again.
Can’t control module:
• Check status of CPU Run green LED. Should be blinking slowly and in
unison with other modules if System module is present. If not, try removing
it and plugging it in again.
• System module may not be working properly if installed.
• Check that the Local/Remote switch on the front of the module is set to the
correct operating mode.
No signals out of module:
• Check status of In OK green LED. Should be lit. If not, check the input
signal for presence and quality.
• Check for presence and locking of reference signal.
• Enable test signal from local or remote control to test signal path.
• Check cabling to input of module.
• Check remote cable equalization by switching the module to Local using
the front panel switch.
