After a Cold Reset, PLL related Registers are reset to default values, however, they are not reset to
default values after a soft-reset (write Reg00). Firmware should not power down the PLL when the PLL
output is used as Stereo_SYSCLK.
7.3.2. I2C and Stereo I2S
The ALC5624 supports I2C for the digital control interface, and I2S/PCM for the digital data interface.
The I2S/PCM audio digital interface is used to input data to a stereo DAC or output data from a stereo
ADC. The I2S/PCM Audio Digital Interface can be configured to Master mode or Slave mode. For the
Stereo I2S Interface, the source clock is always input from MCLK.
Master Mode
In master mode BCLK/SDALRCK/SADLRCK are configured as output. When PLL is disabled and
sel_sysclk=0, MCLK is used as Stereo SYSCLK. When PLL is enabled, MCLK is suggested to provide
13MHz, and PLL should be configured to support 44.1K and 48K base sampling rates. The driver should
set each divider (Reg60 & Reg62) to arrange the clock distribution. Refer to section 12 Appendix A:
Stereo I2S Clock Table, page 69 for details.
Note: The ALC5624 supports different sample rates between SDALRCK and SADLRCK in Master mode.
Slave Mode
In slave mode BCLK/SDALRCK are configured as input. MCLK should provide the BCLK synchronized
clock externally. Stereo_SYSCLK and the driver should set each divider to arrange the clock distribution.
Refer to section 12 Appendix A: Stereo I2S Clock Table, page 69, for details.
Note: In Slave mode, the ALC5624 does NOT support different sample rates between SDALRCK and
SADLRCK. Only SDALRCK is used in slave mode.
