Model 6030

Video-Referenced

AES/Word Clock

Generator
Data Pack

Revision 3.1 SW v1.0.0

MODULE OVERVIEW

The 6030 Video-Referenced AES/Word Clock Generator provides silent AES and word
clock outputs that are locked to a reference video input such as house color black. This
allows digital audio equipment accepting AES or word clock signals to lock to a common
reference produced by the module.

As shown in the block diagram below, you may choose to use a master NTSC or PAL
video reference to the Avenue frame which is distributed to all the frame modules by the
optional System Control module, or an NTSC or PAL video reference connected directly to
the 6030 reference input. In the absence of an external video reference, an on-board oscil­lator will be selected as a reference. The video signal is processed to provide six AES
outputs and two word clock outputs on BNCs at the rear of the frame.

Front panel indicators are provided for monitoring the presence of the external video
reference, the on-board internal reference, the ability of the module to lock to the video
reference as well as power and CPU status.

Control of the module can be from one of the remote Avenue options or from the local
controls on the front of the module. The on-board microprocessor communicates with the
frame for remote control via the System Control module if installed. Module ID (slot
location, software version and board revision) and status information can be monitored by
the frame System Control module and read using the remote control options available.
Software alarms can also be enabled from the remote control options in addition to a
hardware alarm output from the rear 15-pin connector.

Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by an 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.

APPLICATIONS

In most video applications, it is essential that AES sample clocks be locked to a video
reference. In the application shown below, a single 6030 module is used to provide video­locked AES references to multiple 6010 Audio ADC modules.

In the application shown below, a 6030 module is used as master AES reference for an
entire facility. One of the 6030 AES outputs is used as a silent AES signal (“digital audio
black”). Two more outputs are used to lock test signal generators that are used as a source
of test tones. A fourth AES output is used to lock to other digital audio equipment in the
facility. A configuration such as this ensures that all sources in the facility are locked to
video and are synchronous with respect to one another. This reduces the likelihood of
pops, clicks, or other undesirable artifacts when switching between sources.

In the application below, a 6030 module is once again used as a master AES reference for
an entire facility. One of the 6030 AES outputs is used as a silent AES signal (“audio

The word clock outputs of the 6030 are used to lock a digital audio workstation and a
nonlinear video editing system to the rest of the equipment in the facility.

INSTALLATION

Plug the 6030 module into any one of the ten slots in the 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 backplane diagram of the module below for cabling instructions.

Connect an external NTSC or PAL
composite video, color black or
sync signal to the Video In BNC if
using an external reference.

NOTE: Sync minimum of 250 mV.
Signal level maximum of 2 V p-p.

Connect output destinations
to the six AES Out BNCs.

Connect an alarm to the
15-pin connector to
indicate loss of external
reference. Refer to the
pinout below:

MODULE CONFIGURATION AND CONTROL

The parameters for each Avenue module must be configured 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 6030 Parameter Table below summarizes and compares the various con-
figuration 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 6030 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

For troubleshooting purposes, signal presence, module locking status, power and CPU
status can be easily monitored from the front panel of this module using the indicators
explained in the previous section.

If using the Remote mode, the following status items can be monitored using the Avenue
Touch Screen Control Panel or PC Application:

• Module status messages

• External reference present and outputs locked

• Module is generating signals locked to internal crystal oscillator

• Module is unable to lock to video reference

• Slot ID, Software Version and Board Revision

Refer to the overall troubleshooting tips given below for the 6030 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 red 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.

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 lock to Ext Ref indication:

• Check for presence and validity of external reference input signal.

No AES clock signal out of module:

• Check cabling to input of module.
