Notes:
7. S/N measured by CCIR-ARM is 96dB(@fs=48kHz).
8. Input resistance is 16kΩ typically at fs=96kHz.
9. PSR is applied to AVDD, DVDD, PVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
10. S/N measured by CCIR-ARM is 102dB(@fs=48kHz).
11. C_L=20pF, X'tal=24.576MHz, CM1-0= “10”, OCKS= “10”.
12. TVDD=3mA(typ).
13. In the power-down mode. RX inputs are open and all digital input pins including clock pins (MCLK, BICK,
LRCK) are held DVSS.
