MANCHESTER CODING DESCRIPTION
Manchester coding is defined as follows: data is sent during the first half-bit, complementary data is sent
during the second half-bit.

Original data
Manchester coded
The signal average value is constant. This allows clock recovery from the data stream itself. In order to
achieve a correct clock recovery, Manchester coded data must have a duty cycle between:
- 48% and 52% in OOK,
- 45% and 55% in FSK.
PREAMBLE, ID, HEADER WORDS AND MESSAGE DESCRIPTION
The following description applies if the Data Manager is enabled (DME=1).
The ID word is a Manchester coded byte whose content has been previously loaded in the Configuration
Register 2. The complement of the ID word is recognized as an ID word. ID word is sent at the same data rate as
data.
A preamble is required:
- before ID,
- before Header if HE=1,
- before data if HE=0.
It enables:
- in case of OOK modulation, AGC to settle,
- in case of FSK modulation, data slicer reference voltage to settle,
- in any case, clock recovery.
Figure 4 defines the Preamble word in OOK and FSK modulation. Preamble content must be carefully defined in
order not to be decoded as an ID or Header word.
