Web8 aug. 2024 · The transmitter simply has to output a frame of data at a defined bit rate. Contrastingly, the receiver has to recognize the start of the frame to synchronize itself, and therefore determine the best data-sampling point for the bit stream. Figure 2 shows a common method used by a UART receiver to synchronize itself to a received frame.

Assuming bit rate = 250kBits/psec. bit time = 1 / bit rate = 1 / (250 * 1000) s = 4 * s = 4 µs. Therefore, 1 bit will take 4 µs to transfer on the bus when using 250 kBit/s. So, the approximate time to transfer 1 frame is (4 µs/bit * 125 bit) = 500 µs. 2.
