High Quality Digital to Analog Converter with Analog Audio De-embedding Module

The DMA6800 is a broadcast quality SD-SDI to analog video encoder and embedded audio de-multiplexing module with 2ch-3ch analog composite video outputs, 1ch-2ch SDI output with embedded audio and 2ch balanced analog audio output.
The DMA6800 adopts the latest encoding technology that gains high quality video output. The 12-bit decoding handles a variety of signal inputs, and assures the highest quality of the outputs. The 8X oversampling and jitter removal technology ensure the accuracy of the output signal.
Any of the four audio group can be selected for de-embedding. In addition, any two channels from selected audio group can be converted to analog audio.

Features  >>> 

• SDI input with embedded audio, featuring auto-sensing mode
• Up to two channels of SDI distribution outputs with embedded audio
• Up to three channels of 12-bit 8 X oversampling analog composite outputs with broadcast quality

• Two channels of balanced analog video output
  
• Selects any audio group out of four audio groups to be de-embedded
  
• Selects any two channels audio at random out of de-embedded audio groups and converting it into analog audio output
  
• Card-edge control
