Asynchronous Operational Range
The operational range of the Receiver is dependent on the mismatch between the received bit
rate and the internally generated baud rate. If the Transmitter is sending frames at too fast or
too slow bit rates, or the internally generated baud rate of the Receiver does not have a similar
(see
the start bit.
The following equations can be used to calculate the ratio of the incoming data rate and inter-
nal receiver baud rate.
