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. These audio converters can generate fixed-rate Tone signal and provide flexibility in audio sampling and delay setting.

The ADC6820N/ADC6820N4 can receive synchronized signal from video board where the tracking delay is set.
