This results in the following:
For DP:
T :
delay-min
Jitter:
The use of the digital filter in DP increases the jitter by T
For PA (LE = 6):
T :
delay-min
Jitter:
For PA (LE = 7):
T :
delay-min
Jitter:
The use of pulse modulation increases the jitter by T
As a comparison, the values of the DPC31 are shown below (see specification
DPC31 version 1.0):
T :
