1.Response scales with Fs in PCM Mode. Specifications are normalized to Fs and are denormalized by multiplying by Fs. For DSD Mode, Fs is 44.1 kHz.

2.For PCM Single-Speed Mode, N = 1.

For PCM Double-Speed Mode, N = 2.

For PCM Quad-Speed Mode, N = 4.

For PCM Octuple-Speed Mode, N = 8.

For DSD 64 x Fs Mode, N = 1.

For DSD 128 x Fs Mode, N = 1.

3.Required time for the magnitude of the DC component present at the output of the HPF to reach 5% of the applied DC signal.

4.Filter settling time is 0.775 seconds at Fs = 32 kHz.

Table 3-10. DSD Combined Digital and On-Chip Analog Filter Response 1

Test conditions (unless specified otherwise): Digital gains are all set to 0 dB; TA = +25Â°C; PDN_XTAL = 0, MCLK_INT = 1, and MCLK_SRC_SEL = 00

(crystal frequency fXTAL = 22.5792 MHz).
