Abstract: A method of transmitting data over a serial communications interface may include transmitting, from a first device to a second device, a first sequence of bits over the serial communications interface at a first transmission rate. A second sequence of bits may be received by the first device. A third sequence of bits may be generated from the second sequence of bits. The third sequence of bits may include each bit in the second sequence of bits repeated a predetermined number of times but otherwise arranged in the same order as in the second sequence of bits. When the third sequence of bits is transmitted over the serial communication interface at the first transmission rate, the effective transmission rate of the third sequence of bits may be a function of the predetermined number of times each bit is repeated.
