Notes
1. The typical value of the timing is specified at 48 kHz sampling frequency.
2. In order to prevent digital noise interfering with the L3-bus communication, it is best to have the rise and fall times as
3. When the sampling frequency is below 32 kHz, the L3CLOCK cycle must be limited to
4. C
5. After this period, the first clock pulse is generated.
6. To be suppressed by the input filter.
