9 / 41 page [AK4392] MS1045-E-02 2009/04 - 9 - SHARP ROLL-OFF FILTER CHARACTERISTICS (fs = 44.1kHz) (Ta=25 °C; AVDD=VDDL/R=4.75 ∼ 5.25V, DVDD=4.75 ∼ 5.25V; Normal Speed Mode; DEM=OFF; SD bit=“0”) Parameter Symbol min typ max Units Digital Filter Passband (Note 12) ±0.01dB −6.0dB PB 0 - 22.05 20.0 - kHz kHz Stopband (Note 12) SB 24.1 kHz Passband Ripple PR ±0.005 dB Stopband Attenuation SA 100 dB Group Delay (Note 13) GD - 36 - 1/fs Digital Filter + SCF Frequency Response: 0 ∼ 20.0kHz - ±0.2 - dB SHARP ROLL-OFF FILTER CHARACTERISTICS (fs = 96kHz) (Ta=25 °C; AVDD=VDDL/R=4.75 ∼ 5.25V, DVDD=4.75 ∼ 5.25V; Double Speed Mode; DEM=OFF; SD bit=“0”) Parameter Symbol min typ max Units Digital Filter Passband (Note 12) ±0.01dB −6.0dB PB 0 - 48.0 43.5 - kHz kHz Stopband (Note 12) SB 52.5 kHz Passband Ripple PR ±0.005 dB Stopband Attenuation SA 95 dB Group Delay (Note 13) GD - 36 - 1/fs Digital Filter + SCF Frequency Response: 0 ∼ 40.0kHz - ±0.3 - dB SHARP ROLL-OFF FILTER CHARACTERISTICS (fs = 192kHz) (Ta=25 °C; AVDD=VDDL/R=4.75 ∼ 5.25V, DVDD=4.75 ∼ 5.25V; Quad Speed Mode; DEM=OFF; SD bit=“0”) Parameter Symbol min typ max Units Digital Filter Passband (Note 12) ±0.01dB −6.0dB PB 0 - 96.0 87.0 - kHz kHz Stopband (Note 12) SB 105 kHz Passband Ripple PR ±0.005 dB Stopband Attenuation SA 90 dB Group Delay (Note 13) GD - 36 - 1/fs Digital Filter + SCF Frequency Response: 0 ∼ 80.0kHz - +0/ −1 - dB Note 12. The passband and stopband frequencies scale with fs. For example, PB=0.4535×fs (@ ±0.01dB), SB=0.546×fs. Note 13. The calculating delay time which occurred by digital filtering. This time is from setting the 16/20/24bit data of both channels to input register to the output of analog signal. |
