... Freescale Semiconductor, Inc. COMMUNICATION PROTOCOL 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 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 ...
