Abstract
Methods and systems for a digitally controlled oscillator may comprise, for example, an all-digital all digital phase locked loop (ADPLL) for generating an output clock signal from a reference clock signal, the ADPLL comprising a thermometer pulse coder comprising a plurality of frequency control word signal lines. the thermometer pulse coder may be configured to generate a frequency control word from a binary encoded frequency control word, where the frequency control word may comprise hermometer coded signals and a pulse modulated dither signal, and may select a frequency control word signal line over which to transmit the pulse modulated dither signal and may transmit the thermometer coded signals over another of frequency control word signal lines. A digitally controlled oscillator may be configured to receive a frequency control word and generate an output clock signal at a frequency determined using at least the frequency control word.
