2008 7月-12月 第1項課程召集 - (1) 夏季 DAC 原理和製作班 (10月11日繼續組裝)

USB module

6 wire connection.

I am believe DIR9001 can "Overclock itself" to receive sampling rate up to 192KHz.

Let me try some day and tunning something.

To disable the PLL mode in DIR9001 (by connect a fix 24.576MHz) to DIR9001 and set it to non-PLL mode. It may OK.

But it will only support 192KHz, 96KHz and 48KHz input.

If at AUTO mode, I don't know DIR9001 will choose crystal base (24.576MHz or internal PLL), from datasheet say: it choose crystal base first, if the timing is not match, it will jump into PLL mode.

1. For Bal config, it need more components.

2. When using Bal config. Simple connect +VE and GND --> Unbalance output.

3. When you need Bal out, connect +VE, -VE, GND to XLR.

4. You cannot use un-balance to be a balance.

5. The function of LPF are same.
