TLV320AIC3101的配置问题.

我要配置TLV320AIC3101为48KHZ/16BIT

但是我实际测量的WCLK就有51.96KHZ为什么啊?

Write_1_Bit(1,0x80);         //软件复位

  Write_1_Bit(3,0x91);         //PLL使能Q,Q,J配置

  Write_1_Bit(4,0x20);         //J配置

  Write_1_Bit(5,0x80);         //配置D

  Write_1_Bit(6,0x1c);         //配置D

  Write_1_Bit(7,0x00);         //fs=48khz,

  Write_1_Bit(8,0xf0);  

  Write_1_Bit(9,0x00);

  Write_1_Bit(11,0x01);       //配置R

  Write_1_Bit(19,0x80);       //配置MIC1LP/L_AD

  Write_1_Bit(24,0x80);       //配置MIC1LP/R_AD

  Write_1_Bit(25,0x40);       //MICBIAS电压设置

  Write_1_Bit(51,0x08);       //HPLOUT

  Write_1_Bit(65,0x08);       //HPROUT
