Power-down mode (PDN pin = “L”) (Note 13)
Note 5. Measured at LISEL/RISEL pins when the input resistor=47kohm, the feedback resistor=24kohm and input level
=2Vrms.
Note 6. Measured through Pre-Amp -> ADC. Input resistor=47kohm, feedback resistor=24kohm.
Note 7. S/N measured by CCIR-ARM is 96dB(@fs=48kHz).
Note 8. This value is the interchannel isolation between all the channels of the LIN1-6 and RIN1-6.
Note 9. PSR is applied to AVDD, DVDD, PVDD and TVDD with 1kHz, 50mVpp.
Note 10. S/N measured by CCIR-ARM is 102dB(@fs=48kHz).
Note 11. C

=20pF, X'tal=24.576MHz, CM1-0=“10”, CM1-0=“10”, OCKS1-0="10"@48kHz,"00"@96kHz,
"11"@192kHz. Headphone = No output. The resister network is attached to TX pin.
Note 12. TVDD=6mA(typ@fs=48kHz), 7mA(typ@fs=96kHz), 10mA(typ@fs=192kHz).
Note 13. In the power-down mode. RX0 input is open and all digital input pins including clock pins (MCLK2, BICKA,
BICKB, ILRCKA, OLRCKA, BICKB pins) and RX1-3 pins are held DVSS
