Notes:
5. S/N measured by CCIR-ARM is 96dB(@fs=48kHz).
6. For AC-load. 4kfor DC-load
7. PSR is applied to AVDD, DVDD, PVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
8. S/N measured by CCIR-ARM is 102dB(@fs=48kHz).
9. CL=20pF, X'tal=24.576MHz, CM1-0=“10”, CM1-0=“10”, OCKS1-0="10"@48kHz,"00"@96kHz, "11"@192kHz.
10. TVDD=13mA(typ).
11. In the power-down mode. RX inputs are open and all digital input pins including clock pins (MCLK, BICK,
LRCK) are held DVSS.

Notes:
12. The passband and stopband frequencies scale with fs.
For example, 21.8kHz at –0.1dB is 0.454 x fs (DAC). The reference frequency of these responses is 1kHz.
13. The calculating delay time which occurred by digital filtering. This time is from setting the input of analog signal
to setting the 24bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 20/24bit data of both channels on input register to the output of analog
signal.
