Abstract
In general, techniques are described that insert one or more bits into a digital bit stream to maintain an overall transition density in the digital bit stream. Maintaining the overall transition density facilitates the generation of a recovered clock by a phase-locked loop (PLL) circuit of a receiver. For example, when a data transition ratio for a portion of the digital bit stream is less than a desired data transition ratio, the techniques insert additional bits to increase the overall transition density of the digital bit stream.
