Audio Analog to Balanced/Unbalanced AES Converter

The ADC6820N2/ADC6820N4 is an audio A to D converter with audio delay. Both modules can provide two/four balanced audio inputs, two pairs of unbalanced and two pairs of balanced AES audio outputs. They can also provide one balanced or unbalanced DARS input, one Genlock input.
The user can select either DARS or Genlock as a synchronized signal. Both modules can generate fixed-rate Tone signal and provide flexibility in audio sampling and delay setting.
