ELECTRICAL CHARACTERISTICS (continued)

Unless otherwise noted, all characteristics specified with TA = +25°C, VCC = +5V, VDD = +3.3V, system clock (SCKI) is 512fS for Single Rate

Sampling, 256fS for Dual Rate Sampling, or 128fS for Quad Rate Sampling. The device is operated in Master mode for all dynamic performance

measurements.

(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.
