De-Embedder & Audio D/A Converter

The module extract one audio group from SDI input according to BT1305, and then converted to four analog audio outputs. After equalizing and re-clocking of SDI input the audio PLL extracts timing required for audio processing, selecting audio group, delayed up to 340 msec with respect to digital video to solve lip sync problem. Both digital AES3 and analog audio channel are available at the outputs, analog audio is provided by a 128xFs over-sample delta-sigma A/D converter.
Selecting audio group/delay, listen-in stereo jacks, and audio status indicators handled via front panel. BNC connectors for SDI input, active loop-through, De-embedded SDI outputs, and 9-pinD connectors for analog and digital audio outputs are located in the rear panel.
