JUNGER C8840 sync interface card

The C8840 as the heart of a C8000 system. It synchronizes the backplane audio transport to maintain glitch free hand over of serial audio data between the various I/O and processing modules.

For redundant operation it offers two inputs with automatic switch over. This allows the system integrator to design a fail over system with independent feeds which may even have different reference formats (E.g. BB and AES sync).

For Dolby E encoding inside a C8000 frame a frame sync pulse (AKA frame reference) is necessary.
The C8840 extracts such frame sync pulse from the input video reference. A circuit is provided to move the edge of that reference in respect to the input video frame. I.e. one may align a Dolby E encoded signal by the accuracy of a video line to the reference switching point.
If no video reference is connected the frame sync pulse will be generated from the internal sync source.

For non video applications like CD mastering or high resolution audio production the C8840 may be synchronized to audio sample rates of 44.1, 88.21 or 96kHz. Pls. keep in mind that those sample rates can not be used for SDI (Serial Digital Video) embedding / de-embedding.

The C8840 measures the input format and displays it via the Web GUI status display of the module.

In case of a severe sync problem, the Frame Controller can send a SNMP trap and / or activate a SNMP GPO. A higher-ranking monitoring system may poll the status of the sync module(s) via SNMP.

Finally there is the feature to set the sync source via presets loaded by a GPI and to get a GPO for the selected source.
