The device works either in hardware mode (HW mode) or software mode (I2C mode). The default is hardware mode. Software mode is enabled by setting bit 2 of configuration register 0x02. In HW mode, LRCK and SCLK are supplied externally. LRCK and SCLK must be synchronously derived from the system clock with some specific rates. The device can auto detect MCLK/LRCK ratio according to Table 1. The device only supports the MCLK/LRCK ratios listed in Table 1. The SCLK/LRCK ratio is normally 64. ![](http://userimage8.360doc.com/19/0921/13/66196600_201909211337530024803105_wm.png)
CLOCK MODES AND SAMPLING FREQUENCIES In software mode, the device supports standard audio clocks (32Fs, 64F, 128Fs, 256Fs, 384Fs, 512Fs, etc), USB clocks (12/24 MHz), and some common non standard audio clocks (16 MHz, 25 MHz, 26 MHz, etc). According to the serial audio data sampling frequency (Fs), the device can work in two speed modes: single speed mode or double speed mode. In single speed mode, Fs normally ranges from 8 kHz to 48 kHz, and in double speed mode, Fs normally range from 64 kHz to 96 kHz. The device can work either in master clock mode or slave clock mode. In slave mode, LRCK and SCLK are supplied externally, and LRCK and SCLK must be synchronously derived from the system clock with specific rates. In master mode, LRCK and SCLK are derived internally from device master clock.
