Claim Text:
1. A method comprising: storing, with a transmitter, a portion of a digital bit stream; determining, with the transmitter, a data transition ratio between a number of data transitions in the stored portion and a number of digital bits in the stored portion, wherein the number of data transitions comprises a number of instances that a digital bit having a first value is followed by an immediately subsequent digital bit having a second, different value in the digital bits in the stored portion; comparing, with the transmitter, the determined data transition ratio with a desired data transition ratio; and when the determined data transition ratio of the portion of the digital bit stream is less than the desired transition ratio and prior to transmitting a last digital bit of consecutive identical digits that would have caused a recovered clock of a receiver to lose phase and frequency lock, inserting one or more digital bits into the digital bit stream to increase a number of data transitions in the digital bit stream such that the number of data transitions in the digital bit stream relative to a number of digital bits in the digital bit stream exceeds or is equal to the desired data transition ratio.
