(1)Applies to the FMT0, FMT1, FMT2, S/M, FS0, FS1, FS2, HPFD, BCK, LRCK, SUB, DSDCLK, DSD1, DSD2, DSD3, DSD4, and SCKI pins.
(2)Applies to the TEST and RST pins.
(3)Typical performance is measured using an Audio Precision System Two Cascade or Cascade Plus test system. The measurement bandwidth
is limited using the Audio Precision 22Hz high-pass filter in combination with either a 20kHz low-pass filter for fS = 48kHz or a 40kHz low-pass
filter for fS = 96kHz and 192kHz. All A-weighted measurements are performed using the A-weighting filter in combination with the band limiting
filters already mentioned. The measurements are made with the RMS detector selected.
(4)A 256fS system clock is used at final production test for fS = 48kHz measurements.
(5)Typical DSD performance is measured using an Audio Precision System Two Cascade or Cascade Plus test system. The measurement
bandwidth is limited using the Audio Precision 22Hz high-pass filter in combination with a 20kHz low-pass filter. All A-weighted measurements
are performed using the A-weighting filter in combination with the band limiting filter already mentioned. The measurements are made with the
RMS detector selected. The 1-bit DSD data is converted to 24-bit linear PCM data for measurement using a PCM4204 configured for DSD input
mode.
