Abstract: Method and system for a power optimal coding scheme used in data transmission. The coding scheme provides for the transmission and reception of asynchronous data using a first in first out driven serial port. In one embodiment of the present invention, preamble and synchronization word patterns are selected such that the start bit of the first byte of data that follows the synchronization word synchronizes with the start bit clocking signal of the baseband receiving serial port. Thereafter, the data stream will be synchronized with the serial port.
