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
black”). The remaining five AES outputs are used to lock to other digital audio equipment.
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.
