Notes
1.
2.
The typical value of the timing is specified at 48 kHz sampling frequency.
In order to prevent digital noise interfering with the L3-bus communication, it is best to have the rise and fall times as
small as possible.
When the sampling frequency is below 32 kHz, the L3CLOCK cycle must be limited to
1
64fs
cycle.
C
b
is the total capacitance of one bus line in pF. The maximum capacitive load for each bus line is 400 pF.
After this period, the first clock pulse is generated.
To be suppressed by the input filter.
