2.1.6 Baseband receiver
Minimum data pulse width
5uS
Maximum data pulse width
500uS
Typical settling time
50uS from the first transition
Note:
The receiver extracts the mean level of the incoming data stream as
a reference. This takes approximately 50uS; therefore the data
output of the receiver is not valid until after this time.
