Unbalanced/Balanced AES Audio De-embedding Module

The SDX6811N/SDX6812N is an AES/EBU de-embedding module, which de-embeds 4 channels (2 pairs) of AES/EBU audio and supports SDI outputs with equalization and reclocking. The user can choose any channel out of 4 embedded audio groups as an audio output or the user can choose the synthesized audio as an output signal.
Each module has its own distinct feature as follows:
The SDX6811N has unbalanced AES outputs, and the SDX6812N has balanced AES outputs.
