但是“CLK的频率和LRC(采样率/左右选择)的频率之间的关系”呢?,难道他们之间没有什么直接的联系吗,我看了phlips的说明也没有看懂:
In master mode, the RATIO bits in TxConfig must be set to required bit rate.
wishbone _ bus _ clock
bit _ rate =---------------
2 ? ( RATIO + 2)
The sample rate depends on the RES (data resolution) and bit rate:
bit _ rate
sample _ rate =---------
RES ? 2
RATIO bits can then be calculated by:
wishbone _ bus _ clock ? sample _ rate ? RES ? 8
RATIO =---------------------------------
sample _ rate ? RES ? 4
还有一般这种记发表示什么意思哦:
For ADC or DAC sampling rates of 8, 32, 48 or 96kHz, MCLK frequencies of either
12.288MHz (256fs) or 18.432MHz (384fs) can be used.
这里的fs是表是采样率吗? 我不怎么懂。
谢谢啦
