(1)Applies to RATE (pin 5) and S/M (pin 6) inputs.
(2)All typical dynamic performance specifications were measured using an Audio Precision System Two Cascade or Cascade Plus test system and a PCM4201EVM
evaluation module. For Normal Speed operation, the measurement bandwidth is limited using the Audio Precision 22Hz high-pass filter and 20kHz low-pass filter.
For Double Speed mode, the measurement bandwidth is limited using the Audio Precision 22Hz high-pass filter and a user-defined 40kHz low-pass filter (the
fS/2 low pass filter may be utilized with similar results). All A-weighted measurements are made using the Audio Precision A-weighting filter in combination with
the filters previously noted here. Minimum and maximum dynamic performance limits are based upon the capability of the production test solution.
