[参考译文] TAS2553：超低音频输出

伊凡，你好，

很抱歉我在处理项目发布时收到了延迟回复。 我通过使用 BCLK 作为源代码和以下配置序列来解决问题。 幸运的是，我在 TAS2552开发板软件 GUI 中看到了配置详细信息。  

uint8_t Device_config1_Array[2]        ={TAS2553_CFR1,(CFR0_SWS_SHUTDOWN |CFR0_PLL_BCLK)}; //MCLK
uint8_t Device_Status_Array[2]         ={TAS2553_STATUS,0x20};
uint8_t Device_config2_Array[2]        ={TAS2553_CFR2,(CFR2_CLASSD_EN|CFR2_BOOST_EN|CFR2_PLL_EN|CFR2_IVSENSE_EN /*|CFR2_APT_EN*/)};//Reserved. MUST BE WRITTEN TO ZERO DURING CONFIGURATION SEQUENCE as shown in Initialization.
uint8_t Device_config3_Array[2]        ={TAS2553_CFR3, (CFR3_DIN_SOURCE_AVG |CFR3_I2S_OUT_SEL|CFR3_WCLK_22KHZ)}; 
uint8_t Serial_Interface_CTRL_Array[2] ={TAS2553_SERIAL, (SERIAL_WORD_16 | SERIAL_DATA_I2S|SERIAL_CLKPERFRAME_32)}; 
uint8_t Level_ctrlreg_Array[2]         ={TAS2553_LEVEL_CTRL, 0xA9};//Write to 0xA9 during initialization. See Initialization.
uint8_t PGA_Gain_Array[2]              ={TAS2553_PGA_GAIN, PGA_GAIN_10db };//PGA_GAIN_0db

uint8_t PLL_CtrlReg1_Array[2]          ={TAS2553_PLL_REG1,(0x20 &TAS2553_PLL_J_MASK)};  // 24.5760 MHz = (0.5 *J.D*PLLCLK)/2p
uint8_t PLL_CtrlReg2_Array[2]          ={TAS2553_PLL_REG2,TAS2553_PLL_D_UPPER(0x0000)} ; // PLL set, uppder D =0
uint8_t PLL_CtrlReg3_Array[2]          ={TAS2553_PLL_REG3,TAS2553_PLL_D_LOWER(0x0000)} ; // PLL set, Lower D =1
