Note 20. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 21. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
PMVCM = PMPLL = MCKO = PMMIN = PMMP = M/S bits = “1”. MPWR pin outputs 0mA.
AVDD=12mA(typ), DVDD=4mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=11mA(typ), DVDD=3mA(typ).
Note 22. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1”.
Note 23. All digital input pins are fixed to DVDD or DVSS.
Power Consumption for each operation mode
Condtions: Ta=25°C; AVDD=DVDD=HVDD=3.3V; AVSS=DVSS=HVSS=0V; fs=44.1kHz, External Slave Mode,
