Abstract:
A method for reducing data loss in digital communication between asynchronous digital devices, the method comprising the steps of:a) generating a first data transmission stream using a transmitter device, the first data stream synchronous to a first clock signal; b) generating a second data transmission stream using the transmitter device, wherein the second data transmission stream is a copy of the first data stream with a phase shift; c) determining whether the phase of the first clock signal is within a predetermined amount of the phase of a receiver clock signal of a receiver device, wherein the receiver clock signal is used by the receiver device to sample received data; d) transmitting the first data stream to the receiver device when the phase of the first clock signal differs from the phase of the receiver clock signal by greater than the predetermined amount; and e) transmitting the second data stream to the receiver device when the phase of the first clock signal differs from the phase of the receiver clock signal by less than the predetermined amount such that jitter on the first clock signal and receiver clock signal does not disrupt communication between the transmitter device and the receiver device.
