AUDIO ANALOG TO BALANCED/UNBALANCED AES CONVERTER

AUDIO ANALOG TO BALANCED/UNBALANCED AES CONVERTER

The ADC6820N/ADC6820N4 are an audio A to D converter with audio delay. Both two modules can provide two/four balanced audio inputs, two unbalanced and two 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 synchronized signal. The ADC6820/ADC6820N4 can generate fixed-rate Tone signal and provide flexibility in audio sampling and delay setting.
