Table2. AK4126 PLL Mode Setting (Input PORT)
(Note 1) PLL lock range is changed by values of R and C connected by FILT pin. For more further details,
please refer to datasheet: “PLL Loop Filter”.
(Note 2) IBICK should be always and continuously supplied, except when clocks are changed.
(Note 3) IBICK = 32fsi is applied to only two audio data formats of 16bit LSB justified and 16bit I
2
S Compatible.
(Note 4) Please refer to datasheet: “Soft Mute Operation”: “Manual mode”.
(Note 5) Please refer to datasheet: “Soft Mute Operation ”: “Semi-Auto mode”.
